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, 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 singer 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. Aerosmith were America's feisty retort to hard-rocking British groups like the Rolling Stones, the Yardbirds, the Who, Cream, Deep Purple and Led Zeppelin. Almost alone among American bands, Aerosmith matched those British legends in power, intensity, and notoriety. Moreover, they've long since surpassed many of their influences in terms of longevity and popularity.
