Dave Grohl / Josh Homme / John Paul Jones supergroup Them Crooked Vultures has been generating so much excitement recently, it's easy to forget Grohl's other group. Yeah, the Foo Fighters, remember them?

Dave Grohl fans will love the Head Foo's furious drumming on the latest leak from his new supergroup, Them Crooked Vultures' "Elephants." While the song's lyrics are tough to make out, the musical energy comes through loud and clear.

As if there weren't enough bands cluttering Chicago this past weekend, Them Crooked Vultures -- featuring Queens of the Stone Age's Josh Homme on guitar and vocals, Dave Grohl on drums, Led Zeppelin's John Paul Jones on bass and keytar (!), and longtime Queens cohort Alain Johannes on rhythm guitar -- made their not-so-secret debut at the hot, sweaty, and overpacked Metro midnight Sunday.

Brit indie-rock darlings Arctic Monkeys previewed material off their upcoming album while in Australia on a recent tour. Check out footage of the band's performance of all-new track "Crying Lightning" below!
