Aerosmith is an American rock band, sometimes referred to as "the Bad Boys from Boston" and "America's Greatest Rock and Roll Band." Their style, which is rooted in blues-based hard rock, has come to also incorporate elements of pop, heavy metal, and rhythm and blues, and 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 vocalist/pianist/harmonicist Steven Tyler, drummer Joey Kramer, and guitarist Ray Tabano, and formed Aerosmith. In 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 gold and platinum albums, beginning with their 1973 eponymous debut album, followed by their 1974 album Get Your Wings. 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. Two additional albums followed in 1977 and 1979. The band's first five albums have since attained multi-platinum status. Throughout the 1970s, the band toured extensively and charted a dozen Hot 100 singles. By the end of the decade, 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". However, drug addiction and internal conflict took their 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 the album Rock in a Hard Place, which went gold but failed to match their previous successes.
