A couple people mentioned the RAMONES on another thread about bands/albums you've changed your mind on. I never actively disliked them, but the first time I heard them at CBGB's I was in shock. They looked liked they'd leapt from the pages of MAD Magazine and I didn't know if it was a joke, a performance art piece or if they were menatlly retarded. It turned out to be a new breed of good old rock and roll. Who'd have thunk we'd be hearing Hey Ho! Let's Go! blaring out of the speakers at NBA games and on TV adverts well into the new millennium? Who's music was so unexpected it shocked you?
