The new RADIOHEAD album was leaked on the Internet last week. "Hail to the Thief" is scheduled to be released in June but a rough copy that hasn't been mastered found it's way on several sites last week. This was confirmed when Nigel Godrich (their producer) posted on the Radiohead Messageboard:

"Its the rough mixes ....
some tracks not even finished.
aint that a bitch?
Not really what I'd want the world to hear, frankly.
boo."

And in other news, I found this interview with the "guy" that provided the vocals for "Fitter Happier".
