<< Pre-1966 Beatles? Oh my Lord. The Beatles are a great band because of albums like:
Rubber Soul
Revolver
Sgt. Pepper's Loney Hearts Club Band
The Beatles (White Album)
Abbey Road
It is insane to even try to have a discussion about which band is better if you throw out half of each band's catalogue. >>
My opinion is that the more acid they dropped, the worse their music became. Those albums you listed are the acid-induced songs.
Again, in my opinion, they sound more "experimental" than musical. Yellow submarine? Come on. Catchy, yes, but crap nevertheless.
