Akira Boch’s first feature has the breezy appeal of an early sound comedy, the inconsequential story providing an opportunity for lively, affectionate characterization. A shy young woman in the bohemian Echo Park neighborhood of Los Angeles agrees to put up her party-girl best friend, who’s out of work; they form a rock band and start playing clubs, but personal differences strain their partnership. It’s refreshing to see a movie about creative types in LA that isn’t obsessed with the idea of getting ahead in show business; the film, like its characters, takes pleasure in music for its own sake.
