Go geek this Labor Day Weekend. Nerd Up! is what you get when you meld Burning Man and a Castle fetish night with the local comic con — a hedonistic club party and multimedia-gasm of live music, performance, art, games and cosplay (costume play, for the uninitiated). Death Starsky performs live with Sun Signs and U.S. Vita Devoid slithers and shakes with her sassy-sexy burlesque, and Blk. Label X presents a cosplay fashion show (pictured, worn by Necro Genic, photo by Fearie Lilly
). DJs Shard Tek-nique, Nostalgia and others spin as the crowd checks out art by Joe Traina, Catrina Deville, Lorin Hawkins and others. Blake Emory does the live/body painting. $5; before 11 p.m. free for women who wear cosplay, Nerd, Geek, Anime, fantasy or steampunk attire. Doors are at 9 p.m.
