When Tiësto arrived at EDC Vegas via helicopter, we had no idea he'd brought along a special guest for an emotional tribute. Tiësto devoted almost 15 minutes of his set to honor Avicii, and Aloe Blacc joined him on stage to be a part of the tribute. The two artists performed Avicii's hit "Wake Me Up" and the crowd at EDC definitely felt the love. Watch Tiësto and Aloe's arrivals now.
