• Let's Get Lost (1988): Bruce Weber followed around jazz trumpeter and heroin addict Chet Baker on a year-long excursion, "from the West Coast, to the East Coast, to Europe--including a stop at the Cannes Film Festival--with interviews with Chet, colleagues and friends, including dueling insights from his third wife, a former British show girl, and three children in Oklahoma, and from old flame Ruth Young, a sardonically throaty torch singer." Screens tonight at 7 p.m. and 9:20 at the Castro Theatre; $6-9.
• Circle Jerks: Hermosa Beach-based punk outfit named after a homoerotic act of mutual sexual self-gratification--and formed by Black Flag's original singer, Keith Morris, and future Bad Religion guitarist Greg Hetson--return tonight to show the youngins how it's done. They perform along with Hit Me Back and the Last of the Believers. The ear-splitting sounds start at 8 p.m. at Slim's; $17.
