Cosmic Opera Act II: Imbroglio with Fedde Le Grand

Cosmic Opera is back for another, this two-night stand of the organizers are calling an "extrasensory dance event."Fragment—break up into different thoughts? What that means: It's part dance-music concert, part theatrical experience (complete with a story line and actors) and, probably, pretty damn trippy. The Netherlands' Fedde Le Grand, the man behind 2006's massive club hit "Put Your Hands Up for Detroit," is the headliner; tonight, he's joined by heavily hyped remix king Zedd, along with Funkagenda and David Berrie.
