Dave Matthews described the song How to Disappear Completely, from Kid A, something like this (I'm paraphrasing...) "It's like you're running for your life through a jungle of razors, and you just keep pressing on an on, and all of a sudden, just when you're about to give up, you run out onto a cliff, overlooking the most beautiful sunset you've ever witnessed."
Now, I don't care if you don't like Radiohead, or Dave for that matter, but you have to give credit where credit is due. Dave Matthews knows his stuff about music, and if can describe that song with such passion (he loved the whole album as well) then I can't help but think that Radiohead has something good here. Anyone who's heard it knows exactly what I'm talking about...it slowly builds from a high note Yorke is singing (which carries through the rest of this), into a bunch of dissonant chords and effects coming from all angles, and all of a sudden the dissonance resolves and all you have left is Yorke's voice carrying a pitch-perfect tone that brings shivers to me every time.
Even if you hate Radiohead, do yourself a favor and listen to that song, and you should be able to appreciate Radiohead's "unused" talent afterward.
