The JaM Cellars Ballroom located in the historic Napa Valley Opera House is a stunning 650 person bookable venue for music and performing arts. This historic landmark, originally constructed in 1879 can be both a seated theater-style or open-floor venue, featuring a fully licensed bar and VIP gallery for up to 75 guests. The impressive red and gold exterior has been restored, and the stage and sound desk upgraded to support world-class rock, pop, country and jazz artists. Performances here frequently include BottleRock Napa Valley AfterDark shows, world-class jazz artists booked by Blue Note Napa, as well as community arts events.
