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.

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.

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.
