Olivier Abbeloos was born in Aalst, Belgium on January 18th 1969.
He was always interested in music and started to learn how to DJ at age of 13 when he got a DJ setup from his parents. He thinks he started producing at the age of 17 when he amused himself by making mega-mixes on two track recorders.
His first project was L&O "Even Now", but he never got credited on that record and he did several productions on Target label (Neon, L&O, PLB System).
His first project together with Patrick De Meyer was the Beat Machine, The "Mr Zigzag" on PIAS label.
His first most succesfull project was Quadrophonia, together with Lucien Foort.
T99 was first started by Patrick De Meyer releasing three solo works. Patrick later heard Olivier Abbeloos working on a track called "Anasthasia" and proposed Abbeloos to release it as T99. Abbeloos agreed if from that point on they were a group by the name of T99. They later go on together to produce their only album "Children Of Chaos".
