Some supergroups just seems to make sense. After all, George Harrison had already worked with Bob Dylan before the Traveling Wilburys. Same with Eric Clapton and Ginger Baker before Blind Faith, and with Stephen Stills and Neil Young before Crosby Stills Nash and Young.

But, other times, a new supergroup arrives like a bolt out of the blue -- mixing and matching huge names that you might not have guessed shared a musical vocabulary. Or even a musical zip code.

Think of bands like Them Crooked Vultures, which paired Dave Grohl of Foo Fighters with Josh Homme from Queens of the Stone Age and John Paul Jones of Led Zeppelin. There's a group that actually features both Alice Cooper and Paul McCartney (no kidding!), and one with that guy from the Eurythmics and Mick Jagger.
