After Society:Culture House unceremoniously shut its doors last month, Casa Rasta had to find a new venue for Santa Rosa’s best (and only) reggae genre night. Well-known for surprise guest appearances, including J Boog and Los Rakas (pictured), resident deejays Sizzlak and Dinga have now linked with San Francisco sound system, Jah Warrior Shelter to hold down the dancehall each Wednesday beginning Dec. 4 at Christy’s. 99 Old Court House Square, Santa Rosa. 10pm. $5. Ladies free through December.
