Aerosmith has had a fully formed sound from the very beginning of their recording career. Many reviewers noted early on that they sounded like an American version of Led Zeppelin meets the Rolling Stones. They rocked in their own genre-busting way and didn't sound at all like an English band. The Boys from Boston were an American band and it showed. Blues and hard rock propelled them into the spotlight, and they were popular well before they began to be lionized by rock critics the way the Stones were.
