Lollapalooza 2014: Martin Garrix

Dutch house youngster (he's 18; deal with it) Garrix plays the biggest room of all the Lolla after-shows. Pretty telling about the state of modern music, no? He's still flying off on the back of a couple singles, the worldwide smash "Animals" and the more recent "Helicopter." Both are brash bass monsters with glitter on their muscles. With his boyish looks and behemoth drops, he's primed to be the next Zedd/Avicii.
