Hard and pounding: here are the two words that best describe this new Katharsys record. "Trainwreck" is a rather straight, clean and heavy d'n'b number with some heavy hardcore and industrial beats, while the B side is a Katharsys remix of a track originally written by C.A.2K (about whom I don't know anything), and a hell of a rapidfire, staccato tune. Do you need to machine-gun your dancefloor? Here's an adequate record for this.
