Yes, it’s a school night, but that doesn’t bother the lively and loyal crowd on the dance floor at Rock Island. So What, a weekly dance night at this LoDo institution, finds DJs K-Nee, Style ‘N Fashion and Aztec playing just about anything they and the crowd feel like. The Tuesday-night gig grew out of K-Nee’s So What radio show on KUVO eight years ago and has been spinning an eclectic mix of funky, soulful grooves combining acid jazz, Afrobeat, nu jazz, hip-hop and other sounds in various locations ever since. So watcha, watcha, watcha want?
