Martijn “Prowler” started at the end of 1997 with producing music on his PC. From 1997 till 2000 he bought some hardware studio equipment. After that he met some people who gave him the opportunity to perform for an audience with his own music. Prowler decided to send some demo’s to various labels, one of the labels was Cardiac Music. Their reaction was positive and they asked Prowler if he was interested in releasing his tracks on Bionic Recordings. And so Prowler joined the Cardiac crew in October 2003. In a short period of time several tracks where released on this label, such as: Reality, Falling Down, Face of Death and The Paranoid One.
