Pop-Up Gallery & BBQ in the Lower Haight (Friday)
FuncheapSF tipped us off to this "renegade art gallery and BBQ", whereby surrealist painter Jesus Penaloza turns his front porch into a gathering place for local artists and grill enthusiasts from 4 p.m. until 1 a.m., on Haight St. between Pierce and Steiner. (Free, but bring cash in case you want to leave with some new artwork).
Debaser Goes G-Funk @ the Knockout (Saturday)
San Francisco's popular '90s throwback night Debaser targets hip-hop this round. Leave the flannels at home for a party focused on g-funk b-sides and classics. Wear your shell toes and get in free, and best old school sneakers win "an eighth, a forty, and a pager." Otherwise it's $5 to get in, with the St. Ides on special. (9 p.m.)
Wholphin Release Party @ Amnesia (Saturday)
Wholphin, the "DVD magazine of rare and unseen films" celebrates its ninth issue tonight with a screening of short highlights. Included are clips by Spike Jonze, Joseph Gordon-Levitt, and Caveh Zahedi, plus live music from Jeffrey Manson, The Lonesome Heroes, and Dominant Legs. (9 p.m., $7-$10)
Star Party @ Lands End (Saturday)
Looking for a cheap date idea? It don't get more romantic than stargazing. FuncheapSF posted about a "public telescope viewing" at Lands End (USS San Francisco Memorial parking lot). Of course this kinda adventure depends on the cooperation from the fog, but even if you can't see anything but clouds it could make for an evening of cozy cuddling. (7:30 p.m., free)
Dead Prez & Mistah F.A.B. @ Yerba Buena (Sunday)
Local hip-hop powered by the sun. Grind for the Green takes over Yerba Buena Gardens Sunday from 12 to 4 p.m. for free performances by Mistah F.A.B., Dead Prez, and more.
Bayonics @ Union Square (Sunday)
If you're already at Yerba Buena this Sunday, cross Market St. for more local live hip-hop, free of charge. Bayonics' nine-member musical melting pot gives hip-hop Latin flavors and a funk-driven horn section. Check them out in Union Square between 2 and 4 p.m.
Outside Lands on the Cheap (Friday-Sunday)
Can't afford a ticket to Outside Lands? Here's what you do. Plant yourself somewhere in the park and bring along a radio tuned to 90.3 KUSF.
San Francisco's indie-boosting radio station will be streaming
different bands live from the soundboard daily. You won't get to hear
every artist, and the live performances won't last as long into the
night as the festival, but bring a picnic into the woods and this is
your very own budget version of the city's biggest music event.
