“I think this could be our heaviest album yet.”

– Dave Grohl noting (via Rolling Stone) that a bit of Them Crooked Vultures influence might find its way on to the Foo Fighter’s upcoming seventh studio album. According to the Foo’s frontman, the band will work with Nirvana producer Butch Vig, in part to mark the 20th anniversary of Nevermind, and record entirely in analog, using his garage. Testing will begin today. Color us excited.
