As he gets ready to take over the main stage this Friday, Nicky Romero has released a preview of his next single, "Symphonica." As the title suggests, the track is symphonic in nature. A cinematic string-led opening before crescendoing as a stomping house beat comes in and the electric sound design gets louder before a classic Nicky Romero-esque drop.  After initially premiering at last summer's Tomorrowland, the track is comes out on Nicky's own Protocol Recordings on March 25.
