In 2004, eight-year-old Martijn Garritsen watched Tiësto perform at the Olympics and thought, "I could do that." Over a decade later, Garritsen is now Martin Garrix, with a string of game-changing EDM hits to his name. A mainstay of Dutch house giants Spinnin Records, Garrix has mastered the epic drops, addictively bleepy melodies and earthquake-level drum sounds that keep his country at the top of the dance and pop charts. At the same time, his killer edits and uncompromising club vision have led to huge collabs with Dillon Francis, Usher, Sidney Samson and, yes, even Tiësto himself.
