After having made some solo underground records he started working with his buddy Danny van den Berg with whom he produced various club and trance hits under the names of Luna Mora, Danny and Graxx and The Beach house Brothers. Tragically Danny was killed in an accident and Gregor went on solo again. From that moment on Gregor started focussing more on finding his own sound, which appeared to be a little softer and less commercial then the things he had done before.

In the meanwhile Gregor had been living in Madrid, where he met his friend Dr. Kucho!, and shortly after they started producing together. Their first record came out on the Spanish label Weekend Records.

Back in Holland Gregor continued to produce his own sound as well as cooperating with others.

Due to the great diversity in Gregors music, his productions are being played worldwide by soulful djs like for example Roger Sanchez, Bob Sinclar, Harrison Crump, Full Intention and Hardsoul, as well as by deeper house djs like for example Timo Maas, Danny Tenaglia and Seb Fontaine.

In Holland Gregors records are being played by all major funky house djs.

As a dj, Gregor plays a mix of groovy House music with a lot of Soul, Latin, Jazz, Disco and Afro grooves. Hes got a broad experience and is known for his funky sets, having played in Dutch clubs like for example:

Escape, Sinners, More, Paradiso, Panama, Winkel van Sinkel, Las Palmas,  Now and Wow, Loveboat 2.0, Stalker, Bloomingdales, Xo, Praag, De Lichtfabriek, De Rechter, Pepsi Stage, as well as abroad in cities like Moscow, Milano and Madrid

Apart from producing and dj-ing Gregor runs his own record company G-REX Music with Nu-Groove artists like Camiel, Mindel, Rue Rapide, Omaya, Geni Pereira, Marty Belmondo and of course Gregor himself. G-REX specializes in Soul, Latin and Jazz influenced Nu-grooves, from Downtempo to funky House.
