Are they the world's best promise for an awesome supergroup, or will the lesser impulses of these three get the better of them?
As members of three separate bands, these three musicians have already been credited with so much ass-kickery in previous exploits that Them Crooked Vultures' arrival may indeed be the Perfect Storm of Hard Rock. Dave Grohl survived Nirvana to become awesome in his own right. Josh Homme's work in both Kyuss and Queens of the Stone Age is pretty much the definition of stoner rock (which, like, what's cooler than rock for stoners, man). John Paul Jones was in another famous band.
Josh Homme: James Dean and Frank Sinatra's Junkie Lovechild.
Dave Grohl worked with Josh Homme once before on Queens of the Stone Age's Songs For The Deaf. The result was one of the most rockin' albums of the decade. Dave Grohl worked with John Paul Jones on the second disc of the Foo Fighters' album In Your Honor and the subsequent acoustic live shows. The result was Dave Grohl looking like a pretentious fuckwad and writing a bunch of sleepy garbage.
JPJ is there to offer sage-like advice to these whipper-snappers.
Results could be mixed and definitely tough to predict given the album is yet to drop. The project is best left in the hands of Josh Homme. As long as he delegates responsibility within the band it should come together nicely. Given that Homme is about the coolest frontman that either Grohl or Jones has ever encountered, they should do their best to fall in line. As long as he doesn't blow his brains out or write LOTR fanfiction, they should be in good hands.
