You already know that ResFest opens tomorrow at the Palace of Fine Arts. But, did you know that SFist, in conjunction with Larsen Associates (thanks, Chris!), will be giving away passes to the ResFest the rest of the week?

Today's contest is for passes for you and a guest to go see Cinema Electronica (warning: sound, and it's a song that won't get out of your head) at 10 p.m. on Friday, September 23. Cinema Electronica is described as a "selection of the best of contemporary beat-driven music videos", and the sample you get on the ResFest site in no way belies this.

Enter to win by midnight tonight!
