There is a new album of David Bowie covers. It's called Life Beyond Mars. the mini site is nice and you can preview the songs. My favorite is the Au Revoir Simone cover. :)
Au Revoir Simone - Oh! You Pretty Things (Bowie Cover)
I also like this other cover by The Sea and Cake which is not in the new album. I remember it from Andrew Reynold's 2nd part in the Emerica video. He was my hero when I was skating.
