Metallica is an American heavy metal band. The band was formed in 1981 in Los Angeles by vocalist/guitarist James Hetfield and drummer Lars Ulrich and has been based in San Francisco for most of its career. The band's fast tempos, instrumentals and aggressive musicianship made them one of the founding "big four" bands of thrash metal, alongside Megadeth, Anthrax, and Slayer. Metallica's current lineup comprises founding members and primary songwriters Hetfield and Ulrich, longtime lead guitarist Kirk Hammett, and bassist Robert Trujillo. Guitarist Dave Mustaine (who formed Megadeth after being fired from the band) and bassists Ron McGovney, Cliff Burton, and Jason Newsted are former members of the band.

Nirvana was an American rock band formed in Aberdeen, Washington, in 1987. Founded by lead singer and guitarist Kurt Cobain and bassist Krist Novoselic, the band went through a succession of drummers, most notably Chad Channing, and then recruited Dave Grohl in 1990. Nirvana's success popularized alternative rock, and they were often referenced as the figurehead band of Generation X. Their music maintains a popular following and continues to influence modern rock culture.

Green Day is an American rock band formed in the East Bay of California in 1987 by lead vocalist and guitarist Billie Joe Armstrong, together with bassist and backing vocalist Mike Dirnt.

Touring guitarist Jason White became a full-time member in 2012, but returned to his touring role in 2016. Before taking its current name in 1989, Green Day was called Sweet Children, and they were part of the late 1980s/early 1990s Bay Area punk scene that emerged from the 924 Gilman Street club in Berkeley, California. The band's early releases were with the independent record label Lookout! Records. In 1994, their major-label debut Dookie, released through Reprise Records, became a breakout success and eventually shipped over 10 million copies in the U.S. Alongside fellow California punk bands Bad Religion, the Offspring, Rancid, NOFX, Pennywise and Social Distortion, Green Day is credited with popularizing mainstream interest in punk rock in the U.S.

Aerosmith is an American rock band formed in Boston in 1970. The group consists of Steven Tyler (lead vocals), Joe Perry (guitar), Tom Hamilton (bass), Joey Kramer (drums) and Brad Whitford (guitar). Their style, which is rooted in blues-based hard rock, has also incorporated elements of pop rock, heavy metal, glam metal, and rhythm and blues, and has inspired many subsequent rock artists. They are sometimes referred to as "the Bad Boys from Boston" and "America's Greatest Rock and Roll Band". The primary songwriting team of Tyler and Perry is often known as the "Toxic Twins".

Perry and Hamilton, originally in a band together called the Jam Band, met up with Tyler, Kramer, and guitarist Ray Tabano, and formed Aerosmith; in 1971, Tabano was replaced by Whitford. They released a string of multi-platinum albums starting with their eponymous debut in 1973, followed by Get Your Wings in 1974. The band broke into the mainstream with Toys in the Attic (1975) and Rocks (1976). Draw the Line and Night in the Ruts followed in 1977 and 1979. Throughout the 1970s, the band toured extensively and charted a dozen Hot 100 singles, including their first Top 40 hit "Sweet Emotion" and the Top 10 hits "Dream On" and "Walk This Way". By the end of the decade, they were among the most popular hard rock bands in the world and developed a following of fans, often referred to as the "Blue Army". Drug addiction and internal conflict led to the departures of Perry and Whitford in 1979 and 1981. The band did not fare well and the album Rock in a Hard Place (1982) failed to match previous successes.

The Beatles were an English rock band, formed in Liverpool in 1960, that comprised John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band of all time and were integral to the development of 1960s counterculture and popular music's recognition as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways; the band also explored music styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionised many aspects of the music industry and were often publicised as leaders of the era's youth and sociocultural movements.

Black Sabbath were an English rock band formed in Birmingham in 1968 by guitarist Tony Iommi, drummer Bill Ward, bassist Geezer Butler and vocalist Ozzy Osbourne. They are often cited as pioneers of heavy metal music. The band helped define the genre with releases such as Black Sabbath (1970), Paranoid (1970) and Master of Reality (1971). The band had multiple line-up changes following Osbourne's departure in 1979 and Iommi is the only constant member throughout their history.

Robert Nesta Marley was a Jamaican singer, musician, and songwriter. Considered one of the pioneers of reggae, his musical career was marked by fusing elements of reggae, ska, and rocksteady, as well as his distinctive vocal and songwriting style. Marley's contributions to music increased the visibility of Jamaican music worldwide, and made him a global figure in popular culture to this day. Over the course of his career, Marley became known as a Rastafari icon, and he infused his music with a sense of spirituality. He is also considered a global symbol of Jamaican music and culture and identity, and was controversial in his outspoken support for democratic social reforms. In 1976, Marley survived an assassination attempt in his home, which was thought to be politically motivated. He also supported legalisation of marijuana, and advocated for Pan-Africanism.

Audioslave was an American rock supergroup formed in Glendale, California, in 2001. The four-piece band consisted of Soundgarden's lead singer and rhythm guitarist Chris Cornell with Rage Against the Machine members Tom Morello (lead guitar), Tim Commerford (bass/backing vocals), and Brad Wilk (drums). Critics first described Audioslave as a combination of Soundgarden and Rage Against the Machine, but by the band's second album, Out of Exile, it was noted that they had established a separate identity. Their unique sound was created by blending 1970s hard rock and 1990s alternative rock, with musical influences that included 1960s funk, soul and R&B. As with Rage Against the Machine, the band prided themselves on the fact that all sounds on their albums were produced using only guitars, bass, drums, and vocals, with emphasis on Cornell's wide vocal range and Morello's unconventional guitar solos.

The Chemical Brothers are an English electronic music duo formed by Tom Rowlands and Ed Simons in Manchester in 1989.

In the UK, they have had six No. 1 albums and 13 top-20 singles, including two chart-toppers.

Daft Punk were a French electronic music duo formed in 1993 in Paris by Thomas Bangalter and Guy-Manuel de Homem-Christo.

Their longest-serving drummer was Ron Welty, who replaced original drummer James Lilja in 1987 and stayed with the Offspring for 16 years. Welty was replaced by Atom Willard in 2003, who was replaced four years later by Pete Parada, who remained as the drummer for the Offspring until he was fired from the band in 2021 for refusing to get vaccinated against COVID-19. Gregory "Greg K." Kriesel (one of the Offspring's co-founders) was their bassist until 2018, when he was fired from the band due to business disputes, thus leaving Holland as the sole remaining original member. Kriesel was replaced by Todd Morse of H2O, who had been the Offspring's touring guitarist since 2009.

Queen are a British rock band formed in London in 1970 by Freddie Mercury (lead vocals, piano), Brian May (guitar, vocals) and Roger Taylor (drums, vocals), later joined by John Deacon (bass). Their earliest works were influenced by progressive rock, hard rock and heavy metal, but the band gradually ventured into more conventional and radio-friendly works by incorporating further styles, such as arena rock and pop rock.

Before forming Queen, May and Taylor had played together in the band Smile. Mercury was a fan of Smile and encouraged them to experiment with more elaborate stage and recording techniques. He joined in 1970 and suggested the name "Queen". Deacon was recruited in February 1971, before the band released their eponymous debut album in 1973. Queen first charted in the UK with their second album, Queen II, in 1974. Sheer Heart Attack later that year and A Night at the Opera in 1975 brought them international success.

Ender's Game is a 1985 military science fiction novel by American author Orson Scott Card. Set at an unspecified date in Earth's future, the novel presents an imperiled humankind after two conflicts with the Formics, an insectoid alien species they dub the "buggers". In preparation for an anticipated third invasion, children, including the novel's protagonist, Andrew "Ender" Wiggin, are trained from a very young age by putting them through increasingly difficult games, including some in zero gravity, where Ender's tactical genius is revealed.

The book originated as a short story of the same name, published in the August 1977 issue of Analog Science Fiction and Fact. The novel was published on January 15, 1985. Later, by elaborating on characters and plotlines depicted in the novel, Card was able to write additional books in the Ender's Game series. Card also released an updated version of Ender's Game in 1991, changing some political facts to reflect the times more accurately (e.g., to include the recent collapse of the Soviet Union and the end of the Cold War). The novel has been translated into 34 languages.

The Hobbit, or There and Back Again is a children's fantasy novel by English author J. R. R. Tolkien. It was published on 21 September 1937 to wide critical acclaim, being nominated for the Carnegie Medal and awarded a prize from the New York Herald Tribune for best juvenile fiction. The book remains popular and is recognized as a classic in children's literature.

The Hobbit is set within Tolkien's fictional universe and follows the quest of home-loving Bilbo Baggins, the titular hobbit, to win a share of the treasure guarded by Smaug the dragon. Bilbo's journey takes him from light-hearted, rural surroundings into more sinister territory.

The story is told in the form of an episodic quest, and most chapters introduce a specific creature or type of creature of Tolkien's geography. Bilbo gains a new level of maturity, competence, and wisdom by accepting the disreputable, romantic, fey, and adventurous sides of his nature and applying his wits and common sense. The story reaches its climax in the Battle of Five Armies, where many of the characters and creatures from earlier chapters re-emerge to engage in conflict.

Tetris (Russian: Тетрис) is a puzzle video game created by Soviet software engineer Alexey Pajitnov in 1984. It has been published by several companies for multiple platforms, most prominently during a dispute over the appropriation of the rights in the late 1980s. After a significant period of publication by Nintendo, the rights reverted to Pajitnov in 1996, who co-founded the Tetris Company with Henk Rogers to manage licensing.

In Tetris, players complete lines by moving differently shaped pieces (tetrominoes), which descend onto the playing field. The completed lines disappear and grant the player points, and the player can proceed to fill the vacated spaces. The game ends when the uncleared lines reach the top of the playing field. The longer the player can delay this outcome, the higher their score will be. In multiplayer games, players must last longer than their opponents; in certain versions, players can inflict penalties on opponents by completing a significant number of lines. Some versions add variations on the rules, such as three-dimensional displays or a system for reserving pieces.

Several video games based on the Magic: The Gathering franchise exist for multiple systems. Some have attempted to translate the card game to electronic play nearly exactly; others have taken more liberties and drawn more from the setting than the actual rules of the card game. Benefits of successful video game versions of the card game include convenience, practice, and challenge. However, artificial intelligence for a game such as Magic is an extremely hard problem, and such software usually must be continuously updated to stay current with recently released card sets. Video game versions often expand on artwork, and may include unique cards that rely on randomness, effects which would be difficult or annoying to duplicate in real life.

Connect Four (also known as Four Up, Plot Four, Find Four, Four in a Row, Four in a Line, Drop Four, and Gravitrips (in Soviet Union)) is a two-player connection board game in which the players first choose a color and then take turns dropping one colored disc from the top into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own discs. Connect Four is a solved game. The first player can always win by playing the right moves.

The game was first sold under the Connect Four trademark by Milton Bradley in February 1974.

Pinball games are a family of games in which a ball is propelled into a specially designed table where it bounces off various obstacles, scoring points either en route or when it comes to rest. Historically the board was studded with nails called 'pins' and had hollows or pockets which scored points if the ball came to rest in them. Today, pinball is most commonly an arcade game in which the ball is fired into a specially designed cabinet known as a pinball machine, hitting various lights, bumpers, ramps, and other targets depending on its design. The game's object is generally to score as many points as possible by hitting these targets and making various shots with flippers before the ball is lost. Most pinball machines use one ball per turn, and the game ends when the ball(s) from the last turn are lost. The biggest pinball machine manufacturers historically include Bally Manufacturing, Gottlieb, Williams Electronics and Stern Pinball.

Galaga is a 1981 fixed shooter arcade game developed and published by Namco. In North America, it was released by Midway Games. Controlling a starship, the player is tasked with destroying the Galaga forces in each stage while avoiding enemies and projectiles. Some enemies can capture a player's ship via a tractor beam, which can be rescued to transform the player into a “dual fighter” with additional firepower. It is the sequel to Galaxian (1979), Namco's first major hit in arcades.

Development was led by Shigeru Yokoyama and a small team. Initial planning took about two months to finish. Originally developed for the Namco Galaxian arcade board, it was instead shifted to a new system as suggested by Namco's Research and Development division. Inspiration for the dual fighter mechanic was taken from a film that Yokoyama had seen prior to development, where a ship was captured using a large circular beam. The project became immensely popular around the company, with Namco's president Masaya Nakamura even taking interest.

Pong is a table tennis–themed arcade video game, featuring simple two-dimensional graphics, manufactured by Atari and originally released in 1972. It was one of the earliest arcade video games; it was created by Allan Alcorn as a training exercise assigned to him by Atari co-founder Nolan Bushnell, but Bushnell and Atari co-founder Ted Dabney were surprised by the quality of Alcorn's work and decided to manufacture the game. Bushnell based the game's concept on an electronic ping-pong game included in the Magnavox Odyssey, the first home video game console. In response, Magnavox later sued Atari for patent infringement.

Pong was the first commercially successful video game, and it helped to establish the video game industry along with the Magnavox Odyssey. Soon after its release, several companies began producing games that closely mimicked its gameplay. Eventually, Atari's competitors released new types of video games that deviated from Pong's original format to varying degrees, and this, in turn, led Atari to encourage its staff to move beyond Pong and produce more innovative games themselves.

LocoRoco is a platform video game developed by Japan Studio and published by Sony Computer Entertainment, which was released worldwide in 2006 for the PlayStation Portable (PSP) handheld game console. The game was developed by Tsutomu Kouno, striving to create a game that was different from other titles being released for the PSP at the time. After demonstrating a prototype of the core gameplay to his management, Kouno was able to complete development over the course of a year and a half. In LocoRoco, the player must tilt the environment by using the shoulder buttons on the PSP in order to maneuver the LocoRoco, multi-colored jelly-like characters, through each level, being aided by other odd residents while avoiding hazards and the deadly Moja Troop, to reach an end goal.

Patapon is a 2007 video game co-developed by Pyramid and Japan Studio and published by Sony Computer Entertainment for the PlayStation Portable (PSP). The game's unique genre was described to be a combination of rhythm and strategy. The game's concept and design were conceived when game designer Hiroyuki Kotani discovered the Patapon designs from French artist Rolito's personal website.
