Swedish DJ Alesso went from 0 to 100 in just a few short years. At 18, he was already catching the attention of established acts like Groove Armada and David Guetta with his first self-titled EP. Through collaborations with Tove Lo, Dirty South, and Sebastian Ingrosso, he then amassed an army of fans worldwide. He's since performed at some of the biggest dance-music festivals, like EDC and Tomorrowland. And remixes for artists like OneRepublic and Keane have brought his feel-good electro-house to the masses.
