Covered by jazz pianist Brad Mehldau in live concerts and recorded on KCRW's Morning Becomes Eclectic radio show and the Deregulating Jazz radio promo. This instrumental version takes some liberty with the song structure, going into some pretty wild abstractions of the melody during soloing sections. He has also altered the harmony somewhat which, to my ears, makes it sound even more darkly modern than the original. Check this one out, Radiohead fans; I've seen it available on Napster. Mehldau also covers Exit Music (For A Film) on two of his albums, Art of the Trio vols. 3 & 4.
