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. For most of the band's career, they have been a power trio with drummer Tré Cool, who replaced John Kiffmeyer in 1990 before the recording of the band's second studio album, Kerplunk (1991). 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.

Cradle of Filth are an English extreme metal band formed in Suffolk in 1991. The band's musical style evolved initially from black metal to a cleaner and more "produced" amalgam of gothic metal, symphonic metal and other metal subgenres. Their lyrical themes and imagery are heavily influenced by Gothic literature, poetry, mythology and horror films. The band consists of its founding member, vocalist Dani Filth, drummer Martin 'Marthus' Škaroupka, bassist Daniel Firth, guitarists Marek 'Ashok' Šmerda and Donny Burbage, and keyboardist Zoe Marie Federoff.

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.

Disturbed is an American heavy metal band from Chicago, formed in 1994. The band includes vocalist David Draiman, guitarist/keyboardist Dan Donegan, bassist John Moyer, and drummer Mike Wengren.

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 Bloodhound Gang was an American rap rock band from Collegeville, Pennsylvania. It was founded in 1988 by rappers Jimmy Pop and Daddy Long Legs (now in Wolfpac) as a hip-hop group, before branching out into other genres as their career progressed, including punk rock, alternative hip hop, rapcore, funk metal, and electronic rock.

They released an eponymous tape in 1990 before changing their name to the Bloodhound Gang the following year, a reference to "The Bloodhound Gang", a segment on the 1980s PBS kids' show 3-2-1 Contact that featured three young detectives solving mysteries and fighting crime. Franks and Bowe also took on the stage names "Jimmy Pop Ali" (the "Ali" was later dropped) and "Daddy Long Legs", respectively.

Schwichtenberg and Kiske both parted ways with Helloween in 1993; Schwichtenberg died two years later as the result of suicide. Between then and 2016, there had been numerous line-up changes, leaving Grosskopf and Weikath as the only remaining original members. As a septet, their current lineup includes four-fifths of the Keeper of the Seven Keys: Parts I and II-era (1987–1988) lineup, featuring three additional members, vocalist Andi Deris (who had replaced Kiske in 1994), guitarist Sascha Gerstner and drummer Daniel Löble.
