Side Projects: Both Velvet Revolver albums and Happy in Galoshes. I bought 12 Bar Blues and Army of Anyone on iTunes, never got around to getting physical copies.
I also have the 1997 Rolling Stone magazine with STP on the cover in a display case with an STP guitar pick from the 2001 performance of "Revolution" on TV and my Hollywood Bowl 2008 ticket. In short, I've spent way too much money on this damn band. hahaha.
