Timbata is a local septet that specializes in Afro-Cuban music, as well as the many rhythmic derivations from the Caribbean and beyond. Tonight, this group, which has put in the time playing to many happy people under sun and stars, will be hitting it up at the Arcata Playhouse at 7 p.m. Just thinking about the warm luster of the wooden soundscape from the stage to the risers makes me smile ($15).
