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.

Bon Jovi is an American rock band formed in 1983 in Sayreville, New Jersey. It consists of singer Jon Bon Jovi, keyboardist David Bryan, drummer Tico Torres, guitarist Phil X, and bassist Hugh McDonald. Original bassist Alec John Such quit the band in 1994, and longtime guitarist and co-songwriter Richie Sambora left in 2013. The band has been credited with "[bridging] the gap between heavy metal and pop with style and ease".

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. The latter featured "Bohemian Rhapsody", which stayed at number one in the UK for nine weeks and helped popularise the music video format.

The Who are an English rock band formed in London in 1964. Their core lineup consisted of lead vocalist Roger Daltrey, guitarist Pete Townshend, bassist John Entwistle and drummer Keith Moon. They are considered one of the most influential rock bands of the 20th century, and have sold over 100 million records worldwide. Their contributions to rock music include the development of the Marshall Stack, large PA systems, the use of the synthesizer, Entwistle and Moon's influential playing styles, Townshend's feedback and power chord guitar technique, and the development of the rock opera. They are cited as an influence by many hard rock, punk, power pop and mod bands, and their songs are still regularly played. The Who were inducted into the Rock and Roll Hall of Fame in 1990.

Guns N' Roses is an American hard rock band from Los Angeles, California, formed in 1985. When they signed to Geffen Records in 1986, the band comprised vocalist Axl Rose, lead guitarist Slash, rhythm guitarist Izzy Stradlin, bassist Duff McKagan, and drummer Steven Adler. The current lineup consists of Rose, Slash, McKagan, guitarist Richard Fortus, drummer Frank Ferrer and keyboardists Dizzy Reed and Melissa Reese.

Guns N' Roses' debut album, Appetite for Destruction (1987), reached number one on the Billboard 200 a year after its release, on the strength of the top 10 singles "Welcome to the Jungle", "Paradise City", and "Sweet Child o' Mine", the band's only single to reach number one on the Billboard Hot 100. The album has sold approximately 30 million copies worldwide, including 18 million units in the United States, making it the country's bestselling debut album and eleventh-bestselling album. Their next studio album, G N' R Lies (1988), reached number two on the Billboard 200, sold ten million copies worldwide (including five million in the U.S.), and included the top 5 hit "Patience". Use Your Illusion I and Use Your Illusion II, recorded simultaneously and released in 1991, debuted at number two and number one on the Billboard 200 respectively and have sold a combined 35 million copies worldwide (including 14 million units in the U.S.). The Illusion albums included the lead single "You Could Be Mine", covers of "Live and Let Die" and "Knockin' on Heaven's Door", and a trilogy of ballads ("Don't Cry", "November Rain", and "Estranged"), which featured notably high-budget music videos. The records were supported by the Use Your Illusion Tour, a world tour that lasted from 1991 to 1993. The covers album "The Spaghetti Incident?" (1993) was the last studio album to feature Slash and McKagan before their initial departure.

The Rolling Stones are an English rock band formed in London in 1962. Active for six decades, they are one of the most popular and enduring bands of the rock era. In the early 1960s, the Rolling Stones pioneered the gritty, rhythmically driven sound that came to define hard rock. Their first stable line-up consisted of vocalist Mick Jagger, multi-instrumentalist Brian Jones, guitarist Keith Richards, bassist Bill Wyman, and drummer Charlie Watts. During their formative years, Jones was the primary leader: he assembled the band, named it, and drove their sound and image. After Andrew Loog Oldham became the group's manager in 1963, he encouraged them to write their own songs. Jagger and Richards became the primary creative force behind the band, alienating Jones, who had developed a drug addiction that interfered with his ability to contribute meaningfully.
