Blink-182 played a live set at an intimate bash for DJ Steve Aoki‘s 40th birthday, which also raised $500,000 for his foundation.

The band played the surprise jam session at billionaire Ron Burkle‘s Green Acres Estate in Beverly Hills, Calif., for a roomful of just 100 guests — including Tara Reid, Fred Durst, Akon, artist Ron English, DJ Kaskade and Aoki’s family members including his mom and model nieces Olivia and Natalie.

Also performing at the party was T-Pain.

During an auction for the Aoki Foundation guests bid in $25,000 increments, and we hear the birthday boy kicked things off by putting up $50,000 of his own cash. Last year the event raised $250,000. The charity started in 2012 aims to support organizations in the “brain science and research areas.”
