Oakland has its own little thing going on. Case in point: The Stork Club’s Festival of Fitness. Irony meters will overload as hipsters clad self-consciously in spandex, legwarmers, and headbands converge to honor the contributions of Jazzercise and Richard Simmons to ’80s cultural detritus. They’ll probably be drunk, too. The all-day event begins with a barbecue at 2 p.m. and crams twelve performers — such as rock revivalists October Allied and the slightly baffling Gorillas from the Crypt Dance Team — into the next twelve hours. Sunday, June 10. 2 p.m., $8. StorkClubOakland.com
