Passage: Aerosmith is an American rock band formed in Boston, Massachusetts in 1970. The group consists of Steven Tyler (vocals, keyboards), Joe Perry (guitar), Tom Hamilton (bass), Joey Kramer (drums), and Brad Whitford (guitar). Their style, which is rooted in blues-based hard rock, has come to also incorporate elements of pop rock, heavy 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".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, 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 Get Your Wings in 1974. 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. Draw the Line and Night in the Ruts followed in 1977 and 1979 respectively. Their first five albums have since attained multi-platinum status. Throughout the 1970s, the band toured extensively and charted a dozen Billboard 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". However, drug addiction and internal conflict took their toll on the band, which led to 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 was certified gold but failed to match their previous successes.
