Foo Fighter Dave Grohl has teamed up with Jack Black of Tenacious D, and actor Val Kilmer and formed the band Sweetriver and The Huckleberry Dogs. Now, the band isn't really a supergroup per-se, they are a fictional band in the Yahoo web series Ghost Ghirls.
A handful of songs from the show's original soundtrack are available via iTunes, including Sweetriver and the Huckleberry Dogs '70s-style rock jams "Georgia Peach" and "Back to the Beginning."
