BENEFIT: Take advantage of the fact that the Eagle Tavern is open for at least another month and head over to see Thee Oh Sees, Ty Segall, Carletta Sue Kay and The Sandwitches perform a benefit show for KUSF, yet another SF institution whose fate hangs in the balance.

9 p.m. // The Eagle Tavern (398 12th Street) // free

LAUNCH PARTY: Help villagers in Malawi get a clean well by funding their last couple of well parts, as part of WellDone's Launch Party event, which is African themed, featuring African cuisine from Radio Africa Kitchen, a performance by Kuumba African Dance and Drum Ensemble from Stanford University, and fun activities such as a wishing well and photo booth.

6 to 9 p.m. // Public Works (161 Erie Street) // $15-20

ART: Here's your monthly chance to score one-of-a-kind doodles for mere pennies by SF's favorite artists at Sketch Tuesday. Tonight's film projection is 787 Cliparts by Oliver Laric, and resident DJ Pre-K will spin an all-vinal set playing "both kinds of music, rock and roll." Also check out the closing reception for Art Almighty, a group exhibition presented by Last Gasp, while you're there.

6 to 10 p.m. // 111 Minna Gallery (111 Minna Street) // free
