MUSIC: Tonight at the Great American Music Hall, tech professionals from Silicon Valley will loosen the collars on their mock turtlenecks, remove their Clark Kent eyeglasses, and turn into rock stars. Silicon Valley Rocks benefits Music in Schools Today. Tonight's show features Open Source Band (with Jonah Matranga & Randi Zuckerberg), Corinne Marcus & the Kindred Spirits, the Whitehalls, the Tell-Tale Heartbreakers, Farewell Typewriter, and Marrow.

VIDEO GAMES: Are you a Rock Band aficionado frustrated by the lack of public recognition for your virtual jamming talents? Tonight at Umloud, you can hit those colored coded high notes in style. In exchange for a donation to Child's Play Charity, you and your friends can play Rock Band 2 on the main stage at DNA Lounge. That's, like, a real live club audience. Rock Band 2 and The Beatles: Rock Band will also be available for free in the upstairs lounge

7 p.m. // DNA Lounge // $10 for spectators

DANCE: Every other Wednesday Edinburgh Castle Pub hosts 1964, a sixties dance party featuring all the feel-good tunes only played at wedding receptions. Tonight's sock hop will be the last of the aughts. And we all know, there's nothing like old rock and roll to inspire reminiscing about the days of the old.

10 p.m. // Edinburgh Castle (950 Geary) // Free
