Rappers/producers Dr. Dre and Timbaland hosted a surprise concert Wednesday night (Jun 23) at a graduation party at Culver City High School. Dre introduced Timbaland who performed his hits “The Way I Are,” “Promiscuous Girl,” “Say Something” and his most recent single “Carry Out” on a stage inside the school’s gym. Culver City High’s class of 2010 had no idea the Hip-Hop duo was going to be there. During his set, Timbaland asked the students: “Y’all got a curfew?”

The performance was sponsored by Interscope Records and Hewlett-Packard who are both teaming up in an effort to improve digital sound quality. The promo event was recorded for an online documented and featured an HP giveaway/raffle, photos and free food for those who attended. HP said they’d be donating over $10,000 worth of computer equipment to the school.
