Some of the best local bands are coming together for a show tonight at the Great American Music Hall to help turn around one of this city's most serious plights: homelessness. Thee Oh Sees, Sic Alps, Ty Segall and The Sandwitches will shred amps and ear bones all night long for the Coalition on Homeless, so you don't have to feel guilty about spending wads of cash on drinks and band merch on a Wednesday. They're also accepting donations in the form of warm coats, so expect karma points if you bring along last season's jackets to the show!

Doors open at 7:30 pm, show begins at 8 pm. Tickets are $13 in advance, and $16 at the door. Great American Music Hall, 859 O'Farrell St., 415-885-0750.
