Saturday, October 31, 2026, 4:00 AM - 9:00 AM · Grand Star Jazz Club, DTLA, Los Angeles
Underground's annual Halloween masquerade ball takes over two rooms at Grand Star Jazz Club with a costume contest, prizes, and sets from DJ Larry G, DJ Liz O, and DJ Filthy Rich.
A Chinatown relic that feels like stumbling into a ’50s speakeasy where jazz never really left. Grand Star splits its personality between cozy live tunes and DJs spinning everything from dusty standards to hip‑hop throwbacks. Two floors of low lights, a couple of full bars, and a lively crowd make it the sort of place where you linger past last call when the soundtrack morphs from sax solos to old‑school beats.
