Thanks Joost for commenting and paying attention to my ratings. I might say that my ratings are made on base of a relative standard, as in my other thread the Beatles got 10 in popularity and songwriting and the Who got 10 in technical ability.
The Beach Boys. They got 7 in TA in comparison to the other bands. And yes, the vocals also count. But as good as their vocals were (surely the best in the West Coast), I think they weren't much better than the Byrds, Buffalo Springfield and even Jefferson Airplane as all these bands were better than the Beach Boys in playing their instruments.
The Doors. I guess we disagree here. I don't think that Ray Manzarek, Robbie Krieger and John Densmore were excellent musicians, they were just good and competent. Manzarek, in comparison to Rod Argent from the Zombies, sounds like a circus keyboardist to me; Krieger was far behind the best guitarists of the 1960's; Densmore was a decent drummer, but nothing special; and they didn't even have an own bass player. Not to mention Jim Morrison's vocals, he really had no range, despite being the main force of the band. No wonder why they went nowhere after Morrison's death. That said, I really enjoy all the 6 Doors albums made with Jim, but I wouldn't give them more points than I gave to them.
The Byrds. Maybe I was a bit biased here since I love them so much, but I'll try to expain my ratings. They didn't play their instruments only on some songs from their debut record (and McGuinn played his beloved 12-string guitar in every track). I admit they weren't virtuosos, that's why I rate them lower than Jefferson Airplane in TA, but they sound so good together. Roger McGuinn was the master of 12-string guitar; Chris Hillman was a great melodic bass player, in the spirit of Paul McCartney; and Mike Clarke's simple but effective drumming influenced several other drummers in the 1960's (even Ringo I think, from listening to his drumming in Rubber Soul). And their vocals, though not as complex as the Beach Boys, were highly inspiring. About their songwriting, it is true that they did several covers, especially Dylan's songs, but they had excellent songwriters as well. Gene Clark, despite being only in their first two albums, was a first rate songwriter; and Roger McGuinn, David Crosby and Chris Hillman were all good songwriters and each one gave strong contributions. On the other side, Brian Wilson, as great as he was, was almost the exclusive songwriter and ideologist in the Beach Boys. So I gave both bands a deserved 9 in songwriting.
