Musician and producer Jon Brion (Fiona Apple, Aimee Mann, et al.) shows off his ability to play virtually any instrument or song in the rock lexicon -- and beyond -- as host of a popular evening of music every Friday at Largo. Other nights, low-key rock and singer-songwriter fare is offered at this cozy supper club-bar. And when comedy acts come in, about one night a week, they're usually some of the hippest around (Margaret Cho, for example, has been known to appear). Reservations are required for tables, but bar stools are open.
