4. Them Crooked Vultures
Key Members: Dave Grohl (Nirvana, Foo Fighters), Josh Homme (Queens of the Stone Age) and John Paul Jones (Led Zeppelin)
Signature Songs: "New Fang," "Mind Eraser, No Chaser" and "No One Loves Me and Neither Do I"
Current Status: The group released a self-titled album in 2009 and played shows all over the world through 2010, but have been very quiet since then. Grohl and Homme obviously have a lot on their plates, but they say they hope to get around to another Them Crooked Vultures record at some point. It may never happen, but its much more likely than Led Zeppelin touring again.
