The Flaming Lips and Gnarls Barkley join in on the fun

The Killers performed a 45-minute set at Gridlock LA on New Year’s Eve.

The event, which was hosted by Carmen Electra, was held at the Paramount Pictures Studios lot in Hollywood and drew an estimated 5,000 people.

Across town, The Flaming Lips, Gnarls Barkley and Cat Power drew nearly 10,000 people to the newly opened USC Galen Center for a outer space-themed evening. Gnarls Barkley‘s Cee-Lo Green and Danger Mouse donned astronaut costumes and NASA-style jumpsuits for their hour-long set, and headliners The Flaming Lips arrived in a flashing, twirling “spaceship” just in time to ring in the New Year.

Giant Maximus, held in three tents set up in downtown LA, drew approximately 10,000 partygoers for DJ sets by Sasha & Digweed and others. Nearby at the LA Sports Arena, another dance festival, Together As One, drew an estimated 20,000, with headliner Paul Van Dyk beginning his set at 2:30 am.

Just south of LA in Orange County, the OCNYE event at the Orange County Fair Grounds drew an estimated 15,000 for sets by headliner Blondie, Berlin, The English Beat and several other nostalgia-drenched bands.
