It is wild to me how little recognition the Beach Boys and Creedence Clearwater Revival are getting in this discussion of greatest american classic rock bands.
Aerosmith arguably wins the endurance award for putting out new music in 4 different decades that was at least commercially successful (and also has the best ride at any disney park).
Maybe Tom Petty and the Heartbreakers, too, though having their first album in 1976 is stretching the definition of “classic,” at least for my taste. Even Aerosmith had FOUR studio albums by then.
The Byrds are every bit as influential as the Velvet Underground or the Ramones, they just weren’t from New York.
