I completely hear ya. I liked quite a few of their songs back when In Rainbows was released. Really liked that album. But that's until I had my first Radiohead live experience. Then I barely ever listened to their albums again. When I saw the kind of fan base they have, I just couldn't be part of that. It's like they think they're some kind of intellectual music elite, as if the fact your like Radiohead makes you 'sophisticated' or 'superior'. I hated how their behaved during the concert, their claims and all, plus the concert itself was really weak. Really, really weak. After that, barely ever listened to them again. Gave 'em another shot a few months ago but just couldn't get into them anymore. Too hipster for my taste.
now i fucking love radiohead, i will rock the fuck out whenever they play and im going to see them live in a week or so, but your right about their fan base, from what i heard alot of people at their shows kinda stand around not dancing or anything just waiting for the tempo changes and what not and they think thats cool, thats the lame thing about their fan base, other then that there a great band
