With the vocal bomb ‘Summer’ still absolutely crushing the music charts, Calvin Harris returns once again to his own Fly Eye Recordings label to release ‘C.U.B.A.’. Straying away from his typical pop-themed and vocal based productions, C.U.B.A. is more of a hard hitting, bass heavy instrumental. The big room, electro heavy tune — Calvin proves time and time again why he’s one of the best. Not sure whether this will end up on the producer’s upcoming album, but it’ll be available via Beatport soon.
