In a few short years, Sweden's Alesso went from budding producer to EDM headliner to chart-dominating force of nature. With just one record under his belt, the Stockholm musician came under Sebastian Ingrosso's wing; fittingly, Alesso's productions skillfully carry Swedish House Mafia's torch in their mix of earthshaking rave energy and soaring emotional release. He's cemented his status as EDM's top crossover artist by collaborating with Ryan Tedder and remixing OneRepublic, and while he's a natural balladeer, he's just as compelling when laying down lush, widescreen instrumentals.
