It's a tent! It's a theater! It's a fully modular, collapsible, portable music venue, planted smack dab in the middle of the Pepsi Center parking lot during warmer months. Replicating a seasonal venue that's been successful in Boston, CityLights was unfolded last spring as a joint partnership between two powerful local forces, Clear Channel Entertainment and Kroenke Sports. And though the maiden season didn't pack 'em in quite as much the suits might have liked -- due, in part, to a sluggish concert season and a saturated summer-concert calendar -- the tent itself is a lovely, luminous structure with a thoroughly urban feel. Let there be Lights.
