To the Hip Hip Hop

Thirty years after "Rapper's Delight" became the first hip-hop single to go gold, the Sugar Hill Gang (a version of the original group, anyway) is coming to Knoxville for, of all things, the Tennessee Valley Fair. The New Jersey group--definite pioneers of the form, even if their origins as a studio creation of label owner  Sylvia Robinson do murk up the legacy a bit--will be performing alongside more traditional fair fare like Rick Springfield and Molly Hatchet on Friday, Sept. 18.
