Lasers! Look, this is the social contract of EDM festivals: You, DJs and artists, deliver the lasers. The greener the better. Smoke machines, too. We, the crowd, will come with inflatables, glow sticks and neon clothing. Is it any wonder these things are so popular and such a blast? It's Pink Floyd you can dance to. Moby, Nero, PANTyRAiD and more kept the energy levels high and even all evening. Check out images of their performances above. Don't forget the other, more colorful side of the festival, too. The fans. Spin through our pictures of EDM kids from Friday.
