A mask, a hoodie, and a hypnotic beat. This is how Alan Walker, the Norwegian electronic producer who took the world by storm with his track "Faded," emerged in 2015. Today, he boasts over 50 billion streams, collaborations with Sia, Ava Max, and Hans Zimmer, and has performed at Coachella, Tomorrowland, and, of course, his own global tour, Walkerverse.
