MUSIC: The Boiling Suns (east coast transplants/chainsaw rock), Untrust Us (indie/shoegaze), and Whiskey Rebellion (brilliantly genre-free, or let's assume) perform tonight in the Outer Mission. Also, well drinks and pints at the show's venue are a mere $3.00 from 5 p.m. to 9 p.m. Holy smokes!

8 p.m. // El Rio (3158 Mission) // free

EXHIBITION: Ancient Chinese secret, huh? Well, figure out what said secret is at the opening ceremony of the "Chinese Puzzles Exhibition," an exhibition of brain benders (e.g., tangrams, etc.) that will coincide with the Beijing Olympic Games. (Obligatory political aside: Free Tibet! Save Darfur!) The show, it seems, will "give visitors a unique opportunity to learn about these traditional 'intelligence games' and challenge their hands and mind by playing with them." Also, drinks and other assorted refreshments will be served.

6:00 - 8:30 p.m. // 750 Kearny Street, Third Floor (inside the Hilton Hotel) // free
