Here’s Alesso’s live set at the mainstage of Tomorrowland 2013 available for streaming and download. It’s one of the few sets where we actually get the full thing, most are cut down to 20 minute increments or so. Alesso brings it the whole way through, high-energy without relying on too many “pop-house” tracks.
Alesso’ popularity has definitely grown over the past few years, but I don’t think he has the same mainstream draw as Hardwell. Regardless It should be interesting to see where he ranks on the DJ Mag Top 100 this year.
