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.

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.

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.
