Sultan and Ned Shepard made waves last summer with their progressive ballad, "Walls." The track's euphoric melodies and anthemic buildups made it a favorite on dancefloors and festival grounds alike. Now, DJ and production duo The Chainsmokers have brought us a re-working of the song that features a high-energy, thrumming, clubbed-up beat and leaves all the aspects we love about "Walls" untouched. The remix is the first of a series of re-boots by Chainsmokers - make sure to keep posted on their SoundCloud for the next one.
