On this side of the pond, there is a radio program called From the Top hosted by Christopher O'Reilly. (He's quite a pianist!). Anyway, he was in Portland for a piano festival last summer, where he played a recital, including his own arrangements for piano of Radiohead music. He's quite hooked on the stuff, although I couldn't tell the difference from one piece to the next, either composionally nor harmonically. It just didn't float my boat. But if it would help, there's probably a web site out there on either Chris or the radio show that would offer up some more info on them.
