He did even better than that. Before his last studio album was released, he went into a studio and recorded an entire fake album in 24 hours then leaked it to the net.

Funny thing is, a few of the "fake" tracks are better than the real ones that ended up on the album, such as this: http://www.youtube.com/watch?v=rTKRckEmKZQ#t=0m22s (a user created music video for the fake "Dr Yang" - the real version kinda sucks)

Another prime example was "For Those of Y'all Who Wear Fanny Packs" from the Naked Baby Photos album. It's a totally impromptu 6/7 minute "song" performed totally on the spot by him and his band. No prepared lyrics, music, or anything - they just riff off each other.
