The star joins his Queens Of The Stone Age buddies onstage again...

DAVE GROHL was the surprise guest at MONDO GENERATOR’s LA show on Wednesday (April 24).

The group are the brainchild of Queens Of The Stone Age star Nick Oliveri.

The show at the Troubadour venue featured an unusual line-up of Nick and Queens Of The Stone Age bandmate Josh Homme, Twiggy Ramirez from Marilyn Manson‘s band on bass and Dave Grohl on drums.

Grohl has recently been devoting much of his time to collaborating with Queens Of The Stone Age, appearing on much of their new album ‘Songs For The Deaf’. He will also play on the group’s forthcoming US tour.
