The Deep Groove Society hosts its fourth annual "Rage of Sagittarius" event at the Jam at 9 p.m. ($10). The house-tinged electronic dance fiasco will feature a light show by Fred at Marmelade Sky, performances by artists/Djs/ambassadors of sound Marjo Lak, Eureka's Chris Renz aka Baggadonuts, and Jan Van Lier as well a special performance by Susie Kidd. It should be a big, packed, electro blast.
