Twitter was ablaze with TomorrowWorld hate for it being 21+, and judging by the first acts announced for America's TomorrowWorld festival, they'll be mighty upset to miss this. The acts announced run the gamut from Swedish house to filthy dubstep, and should make for an interesting festival. Check out who has been announced, so far:

Axwell | Sebastian Ingrosso | Alesso
Excision | Rusko | Gramatik | Zomboy
Delta Heavy | Figure | Savoy | Grandtheft
NiT GriT | Sound Remedy
