The first official clip of Crooked Vultures rehearsing has appeared online and you can see it below.

The band is a supergroup featuring QOTSA's Josh Homme, Foo Fighters' Dave Grohl and Led Zeppelin bassist John Paul Jones.

That's quite a riff... looks like Homme on guitars, Grohl on drums and Jones on bass...

And check out some live footage of the band playing 'Dead End Friends' in Amsterdam earlier this week. Sounds a bit like Nirvana...
