Did you see Martijn Garritsen at Ultra 2013? Maybe you walked right past him, asked him for a light, or made idle chitchat with him in the line for the port-a-john. Then 16, he was just another face in the crowd.
Today, you may know the Dutch teen by his stage name, Martin Garrix. And there was no missing him at Ultra 2014. He was the ruddy-faced kid jumping around the main stage and getting rowdy with his mom.
"She never saw such a big production," Garrix says. "And for her, it was also like, 'Fuck, it's ridiculous what my son is doing.'"
