Aerosmith is an American hard rock band, sometimes referred to as "The Bad Boys from Boston" and "America's Greatest Rock and Roll Band". Their style, rooted in blues-based hard rock, has come to also incorporate elements of pop, heavy metal, glam, and rhythm and blues, which has inspired many subsequent rock artists. The band was formed in Boston, Massachusetts in 1970. Guitarist Joe Perry and bassist Tom Hamilton, originally in a band together called the Jam Band, met up with singer Steven Tyler, drummer Joey Kramer, and guitarist Ray Tabano, and formed Aerosmith. By 1971, Tabano was replaced by Brad Whitford, and the band began developing a following in Boston.

They were signed to Columbia Records in 1972 and released a string of multi-platinum albums, beginning with their 1973 eponymous debut album. In 1975, the band broke into the mainstream with the album Toys in the Attic, and their 1976 follow-up Rocks cemented their status as hard rock superstars. By the end of the 1970s, they were among the most popular hard rock bands in the world and developed a loyal following of fans, often referred to as the "Blue Army".Davis, p. 239 However, drug addiction and internal conflict took its toll on the band, which resulted in the departures of Perry and Whitford, in 1979 and 1981 respectively. They were replaced by Jimmy Crespo and Rick Dufay. The band did not fare well between 1980 and 1984, releasing a lone album, Rock in a Hard Place, which went gold but failed to match their previous successes.

Although Perry and Whitford returned in 1984 and the band signed a new deal with Geffen Records, it wasn't until the band sobered up and released 1987's Permanent Vacation that they regained the level of popularity they had experienced in the 1970s. Throughout the late 1980s and 1990s, the band scored several hits and won numerous awards for music from the multi-platinum albums Pump (1989), Get a Grip (1993), and Nine Lives (1997). Their comeback has been described as one of the most remarkable and spectacular in rock 'n' roll history. After 38 years of performing, the band continues to tour and record music to this day.

Aerosmith is the bestselling American hard rock band of all time, having sold 150 million albums worldwide, including 66.5 million albums in the United States alone. They also hold the record for the most gold and multi-platinum albums by an American group. The band has scored 21 Top 40 hits on the Billboard Hot 100, nine #1 Mainstream Rock hits, four Grammy Awards, and ten MTV Video Music Awards. They were inducted into the Rock and Roll Hall of Fame in 2001, and in 2005 they were ranked #57 in Rolling Stone magazine's 100 Greatest Artists of All Time.
