Sebastian Moore is back with a blast! CAT5 stands for Category 5 and in this case we are judging with 5 categories.. Sebastian's work has been supported by djs varying from Tiesto to Armin to Ferry Corsten to Markus Schulz and back down the range so its no surprise that this track is destined for the big league. A grooving monster with killer stabs and on top some of Sebastian's signature string and synth lines.
