The Foo Fighters were joined by Lady Gaga and Tony Bennett for a special show in California on Thursday night (08Jan15).
Dave Grohl's band rocked the intimate Belly Up venue in Solana Beach as part of a private party for their talent agency, William Morris Endeavor, and they were joined on the line-up by other stars on the company's roster, including Gaga, Bennett and singer Aloe Blacc.
The stars all performed at the tiny 600-capacity venue, and after the show Gaga tweeted a picture of herself and revealed Foo Fighters frontman Grohl delighted the crowd by playing his guitar with an empty shot glass.
She wrote, "The Foo Fighters were so incredible tonight, monster fury rock n' roll, 20 years of locked precision. Can't stop screaming..."
