Kostrok hails from the Spanish city of Valencia. It consists of two young DJ/producers, José Martí and Adrián Lurbe. Together they founded the Kostrokclub, a multidisciplinary workspace in Turia that houses different artists' initiatives. After working on their musical skills they rocked dance festivals all over Europe and joined the stage with the likes of Skrillex, Crookers, Crystal Fighters and 2 Many DJ's. In the beginning of 2012 they started writing their own material and six months later, after a bidding war between all the main electronic music labels in Europe, they released their first single called Right Now.
