Why it matters
Sweetwater carries a long Marin County music history into a different room. The original tavern opened on Throckmorton Avenue in 1972 and closed in 2007; the present music hall opened in 2012. That distinction keeps the old legends in their proper setting while leaving room for new ones. Today's hall pairs a standing concert floor with a cafe, and its recent live recordings show that extended, exploratory playing remains part of the appeal.
