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.

(Achille) Claude Debussy (French: [aʃil klod dəbysi]; 22 August 1862 – 25 March 1918) was a French composer. He is sometimes seen as the first Impressionist composer, although he vigorously rejected the term. He was among the most influential composers of the late 19th and early 20th centuries.

Born to a family of modest means and little cultural involvement, Debussy showed enough musical talent to be admitted at the age of ten to France's leading music college, the Conservatoire de Paris. He originally studied the piano, but found his vocation in innovative composition, despite the disapproval of the Conservatoire's conservative professors. He took many years to develop his mature style, and was nearly 40 when he achieved international fame in 1902 with the only opera he completed, Pelléas et Mélisande.

Eluveitie is a Swiss folk metal band from Winterthur, Zürich, founded in 2002 by Chrigel Glanzmann. The project's first demo, Vên, was released in 2003.

In November 2007, Eluveitie was signed by Nuclear Blast. The group rose to fame following the release of their first major-label album, Slania, in February 2008.

She recorded an album while signed to Columbia Records, but was dropped before signing to Capitol Records.

Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter. Her discography spans multiple genres, and her songwriting—often inspired by her personal life—has received critical praise and wide media coverage. Born in West Reading, Pennsylvania, Swift moved to Nashville at age 14 to become a country artist. She signed a songwriting deal with Sony/ATV Music Publishing in 2004 and a recording contract with Big Machine Records in 2005. Her 2006 self-titled debut album made her the first female country singer to write or co-write a U.S. platinum-certified album entirely.

Swift's next albums, Fearless (2008) and Speak Now (2010), explored country pop. The former's "Love Story" and "You Belong with Me" were the first country songs to top the U.S. pop and all-genre airplay charts, respectively. She experimented with rock and electronic styles on Red (2012), which featured her first Billboard Hot 100 number-one song, "We Are Never Ever Getting Back Together", and eschewed her country image in her synth-pop album, 1989 (2014), supported by chart-topping songs "Shake It Off", "Blank Space", and "Bad Blood". Media scrutiny inspired the urban-flavored Reputation (2017) and its number-one single "Look What You Made Me Do".

Sabaton is a Swedish heavy metal band from Falun, Sweden. The vast majority of their albums are written about historical events, mainly wars and significant battles. Sabaton has been referred to as one of the "big four" power metal bands, along with Helloween, Blind Guardian and DragonForce. They are one of the most successful metal bands in Swedish history, with their album Carolus Rex being the best-selling Swedish heavy metal album of all time.

Sabaton was formed in December 1999. After the first songs were recorded in Peter Tägtgren's studio, The Abyss, Sabaton was contacted by a couple of record labels. The band signed with the Italian label Underground Symphony, which then released, internationally, the promo CD Fist for Fight. The disc, distilled from two demo tapes recorded between 1999 and 2000, was intended to promote forthcoming Sabaton releases. In 2002, a new album, Metalizer was recorded and was supposed to be distributed by Underground Symphony as the band's debut album. After two years of waiting, during which the band held various performances across Sweden, the album was abandoned.

Amon Amarth () is a Swedish melodic death metal band from Tumba, formed in 1992. The band takes its name from the Sindarin name of Mount Doom, a volcano in J. R. R. Tolkien's Middle-earth. Their lyrics mostly deal with Viking mythology and history, and so they have been sometimes erroneously labeled "Viking metal", although the band insists they play melodic death metal.

The band is composed of lead guitarist Olavi Mikkonen, vocalist Johan Hegg, bassist Ted Lundström, rhythm guitarist Johan Söderberg, and drummer Jocke Wallgren. Amon Amarth has released 12 studio albums, one compilation album, one EP, one video album, and ten music videos. Their first studio album, Once Sent from the Golden Hall, debuted in 1998. Five more studio releases followed, before the band saw its breakthrough with the 2008 album Twilight of the Thunder God, which debuted at No. 10 on the Swedish album charts and No. 50 on the US Billboard 200. Five more albums, Surtur Rising, Deceiver of the Gods, Jomsviking, Berserker, and The Great Heathen Army followed in 2011, 2013, 2016, 2019, and 2022 respectively.

Ludwig van Beethoven (baptised 17 December 1770 – 26 March 1827) was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western music; his works rank amongst the most performed of the classical music repertoire and span the transition from the Classical period to the Romantic era in classical music. His career has conventionally been divided into early, middle, and late periods. His early period, during which he forged his craft, is typically considered to have lasted until 1802. From 1802 to around 1812, his middle period showed an individual development from the styles of Joseph Haydn and Wolfgang Amadeus Mozart, and is sometimes characterized as heroic. During this time, he began to grow increasingly deaf. In his late period, from 1812 to 1827, he extended his innovations in musical form and expression.

Frédéric François Chopin (born Fryderyk Franciszek Chopin; 1 March 1810 – 17 October 1849) was a Polish composer and virtuoso pianist of the Romantic period, who wrote primarily for solo piano. He has maintained worldwide renown as a leading musician of his era, one whose "poetic genius was based on a professional technique that was without equal in his generation".

Chopin was born in Żelazowa Wola in the Duchy of Warsaw and grew up in Warsaw, which in 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising. At 21, he settled in Paris. Thereafter – in the last 18 years of his life – he gave only 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and by giving piano lessons, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his other musical contemporaries, including Robert Schumann.

Wolfgang Amadeus Mozart, baptised as Joannes Chrysostomus Wolfgangus Theophilus Mozart, was a prolific and influential composer of the Classical period. Despite his short life, his rapid pace of composition resulted in more than 800 works of virtually every genre of his time. Many of these compositions are acknowledged as pinnacles of the symphonic, concertante, chamber, operatic, and choral repertoire. Mozart is widely regarded as among the greatest composers in the history of Western music, with his music admired for its "melodic beauty, its formal elegance and its richness of harmony and texture".

Sirenia is a Norwegian gothic metal band from Stavanger, founded in 2001 by Morten Veland.

Buck-Tick (stylized as BUCK-TICK) is a Japanese rock band, formed in Fujioka, Gunma in 1983. The group has consisted of lead vocalist Atsushi Sakurai, lead guitarist Hisashi Imai, rhythm guitarist Hidehiko Hoshino, bassist Yutaka Higuchi and drummer Toll Yagami since 1985. The band has experimented with many different genres of music throughout their three decade career, including punk rock, industrial rock and gothic rock. Buck-Tick are commonly credited as one of the founders of the visual kei movement. They have released 22 studio albums, nearly all reaching the top ten on the charts.

Buck-Tick was originally formed in 1983. All five of the band members lived in Gunma prefecture. Hisashi Imai originally had the idea for the band, and wanted to start despite not being able to play any instruments at the time. He recruited his friend, Yutaka Higuchi, and the two of them began to practice—Imai on guitar and Higuchi on bass. Then, Higuchi asked Hidehiko Hoshino, who had been his friend since their first year of high school, to join. Higuchi tried to convince Hoshino to become the vocalist because of his looks, but Hoshino was more interested in playing the guitar, and did not want to be in the spotlight, so Imai's friend Araki became the vocalist instead. Atsushi Sakurai, a rebellious loner in Imai's class who hung out with the bad-kid Yankī crowd, volunteered to be the drummer. The Buck-Tick members went to high school with Boøwy singer Kyosuke Himuro.
