At today's "organic noise happy hour" contest at Now That's Class, you can only make noise by using your mouth, throat, limbs or any other part of your body. No additional electronics or instruments are allowed. Of course, the club is encouraging humor and creativity. And yes, there are prizes. First place gets a $25 bar tab. Runner up will receive a copy of the new Mr. California 7-inch. Three judges will determine the winner based on talent, crowd response, creativity and stage presence. It all starts at 5 p.m. Admission is free. (Niesel)
