Start your week off with laughter at the Punch Line Comedy Club with autobiographical storyteller and comedian Tommy Johnagin. On Thursday, make sure not to miss Hard SF with the Chemical Brothers at The Armory, and then catch the unofficial after party at Public Works with Blicksmix – Deep House & Minimal Techno. Ratatat return with a vengeance at Regency Ballroom on Friday night, and Jimmy Edgar and Mykki Blanco take over Mezzanine. If more comedy is what you’re craving, head over to Cobb’s Comedy Club for the hilarious musical comedian female duo Garfunkel and Oates. This weekend, it's the original "melting pot" of street fairs, the Nihonmachi Street Fair over in Japantown. On Saturday, don’t miss Benji B + Friends at Mezzanine, and then get dusty at the Dusty Rhino Pre-Burn party at Public Works. On Sunday, celebrate one of SF's favorite icons, Jerry Garcia over at the Jerry Garcia Amphitheater, then pack a picnic for Mary Chapin Carpenter and Bhi Bhiman at Stern Grove.
