The album is stone brilliant. It's at the top of my iTunes playlists and it's what I put on whenever I need a boost. It's made me dig out the White Album again and listen to it with fresh ears. I think it's the most important album of the 21st Century (to date, at least).
Now someone has made a video for one of the Grey Album tracks, "Encore," in which black and white Beatles footage (I'm guessing "A Hard Day's Night") and desaturated footage from a Jay-Zee performance are artfully combined with new footage and CGI (Ringo scratching! John breakdancing!) to make one of the funniest, coolest, and most illegal music videos I've ever seen. Go download it now before the lawsuits start.
