Back in April (2015), we saw Tommy Trash and Wax Motif transform their hard-hitting festival anthem, "Hex" (originally released by Nicky Romero‘s Protocol Recordings), into a beautiful classical music masterpiece. On July 4, Sensation ‘The Legacy’ took place at Holland's Amsterdam Arena, and was live streamed for the world to see via Beatport. The 40,000 people dressed in white to celebrate 15 years of the world’s leading dance music event were treated to a very special performance by a live orchestra, who performed Tiesto's classic trance anthem, "Adagio For Strings." The captivating performance meshed wonderfully with the unique setting of Sensation, proving once again why its considered one of the world's premier events. Check out the performance above.
