Under the alias of Faustix, Morten Brangstrup Olsen has specialized in electro-house and trap strains of commercial EDM. Within only a couple years of discovering a fascination with music production and DJ'ing, the Copenhagen, Denmark native became prolific -- around the dawn of the 2010s -- with a continuous flow of singles, EPs, and remixes. Early on, he found an admirer in Diplo, who sought him to co-produce "Revolution," a 2013 single that reached number 20 on Billboard's Hot Dance/Electronic Songs chart in the U.S. Three years later, after he had signed with the Denmark division of Warner Music, Olsen scored his first Top 40 hit in his home country with "Come Closer," a pop-oriented collaboration with vocalist David Jay. The following year, "Watching You," recorded with fellow producer Alvaro, became another crossover smash. By then, Olsen had become a staple of the global music-festival circuit and had added Icona Pop ("Just Another Night"), Pegboard Nerds ("Emoji"), and David Guetta ("This One's for You") to his list of remix clients. ~ Andy Kellman, Rovi
