Thomas was born in 1969. He began his musical carreer as computer games music composer : after leaving school, he did some jobs to earn money and to build up his own little studio. Together with some friends of his brother liked the idea of building up a little C64 group to create games and demos on computers (first C64 then Amiga, PC & Playstation). After some demos they did their first own game : Gordian Tomb. His first music in a game was Blue Angel 69 by Blue Byte.

In 1993 he founded his own records company : Activate Music productions. In 1994 he created the A-Team with the 3 others producers and songwriters Mike Griesheimer, Andreas Hoetter and Alexander Stiepler. The fruit of their collaboration was the amazing euro project Activate.

Then he started his more successful act, 666, which sold several millions records worldwide.
