The eight-hour May Daze dance party boogies on down to Metropolis in its third year with a lineup that covers the spectrum of electronic music. Four rooms of DJs and live performers play house, techno, dubstep, and lots in between. Headliners include L.A. spinner D:Fuse, British drum & bass vet Tech Itch, and New York's techno-fueled Atomic Babies. Plenty of local DJs will also be on hand: Greg Zorn, Vinny Peace, DJ Leash, Hoppa, Vega, the Synthian, Test60six, and Evan Evolution will all spin till the breakadawn.
