There's a new tour in town and its name is Chaotica. The tour, which scrambles through the country this summer, is none other than the Organic Tour. Concert promoters decided to rename the event that features The Orb, Prodigy, Meat Beat Manifesto and, of course, the ubiquitous Chemical Brothers. In the true sense of the all-night rave, organizers hope the event will run eight hours, starting at 9 p.m. and lasting until just before the sun comes up. (AB)
