I knew Beck was all over this project but I had no idea that there were so many demos and alternate versions floating about the internetz! From last year's most underrated movie, Scott Pilgrim vs. The World we have FOUR unreleased tracks from the man himself. "Indefatigable" was originially recorded and used in the movie but for some reason or another didn't end up on the official soundtrack. "No Fun" is a demo of the song that was eventually recorded by Sex Bob-Omb for the movie. "Disgusting Rainbow" and "Gasoline Eyes" were both recorded by Beck with Brian LeBarton in addition to a whole other messload of songs that never surfaced.
A very special hat tip to Whiskeyclone as per usual for being such a wealth of information on all things Beck.
Also, if you haven't seen the movie yet, I STRONGLY suggest that you do.
