How to make the last night of the year not become the biggest letdown of the year? We've done countless comprehensive roundups in the past, but this year, we keep it simple: three respectably large shindigs with a mix of DJs and live amusements that seem most promising for a blissful last bang on Fri., Dec. 31. L.A.'s most colorful underground partiers will flock to NEXUS 2011 (A Union of Tribes), an arty dress-up party from Blue Insomnia, Ninja Skillz, Project Alma and Curious Josh. House-heads, burners, neo-hippies, whatever you wanna call 'em, the crowd at this one will be creative and welcoming to all. What more can ya ask for? 613 Imperial Warehouse, dwntwn. DJ and performance info plus tickets at blueinsomnia.com/nexus2011.html. Hear Gallery and L.A. Record's Decadence Ball NYE 2011 will get down onstage before the countdown (Abe Vigoda headlines), and DJs including Dan Collins, Dia, Short Shorts and Dirty Dave stomp throughout. Live art show, vendors and food trucks on site. Five Star Bar, 267 S. Main St., dwntwn.; larecord.com. Brave souls venturing into Hollywood have much to chose from, and so did we when we weeded through 'em all. Our pick worth battling the bumper-to-bumpers? The Roosevelt Hotel's NYE 2011, featuring HybriDigital, Shiny Toy Guns, EC Twins, Rick Rude, CC Sheffield and others. Presented by Homemade L.A. and the Alliance, this bash should be bumpin' with some of the most beautiful people on the boulevard. 7000 Hollywood Blvd., Hlywd.; homemadela.com.
