Three years ago, artist Susie Frazier Mueller embarked on an ambitious quest to rejuvenate downtown Cleveland when she founded the annual "Sparx in the City" art-gallery hop. To piggyback on the popular tours, Mueller and a core of volunteers established the Street Beats performance series. Mueller and company hire an ultraeclectic array of entertainers, from the stiltwalking trio Pick-Up Stix to DJ-artist threesome 2% Milk and hip-hop harmonizers Added FX. "Cuyahoga County's creative class is alive and well in downtown Cleveland," said Commissioner Jimmy Dimora at Street Beats' kickoff party at the House of Blues in June. "They are our front-line soldiers. So let the party begin!"
