Defined by its intricate footwork, nuanced upper body movements, acrobatic stunts, and liquefied flow, turf dancing is a method of movement that Oakland can claim all its own. Born out of the city’s streets some two decades ago, the dance style has experienced a renaissance in recent years, in large part thanks to TURFInc, an organization devoted to preserving the style’s legacy and continued relevance. While turf dancing, which is an acronym for “Taking Up Room on the dance Floor,” has its own unique style, TURFInc founder and CEO Johnny Lopez included the “Inc” as a reference to incorporating other dance styles, which often include crumping, bonebreaking, cutting, jookin, boogaloo (another Oakland original), tutting, waacking, strutting, and flexing. In collaboration with Oaktown Indie Mayhem, TURFInc is hosting the second annual “Purge” at the Starline Social Club (645 W. Grand Ave., Oakland) on October 24. The Halloween-themed dance battle will pit the best Bay Area crews against each other for a chance to win prizes and, of course, bragging rights.
