After having studied with mastermusician Ferdinand Povel, finishing with a Master’s Degree at the "Amsterdam School of the Arts", he spent a couple of months in New York, where he had private tuition from players the caliber of Ralph Moore and Joe Lovano.

In 1992 Jason was honored for "Outstanding Musicianship" at the convention of the International Association of Jazz Educators in Miami, USA, where he was invited to perform.

Leading his own bands was always an inner urge and with the release of his debut album "Patience" in August 1996- accompanied by german pianist WalterLang, Belgian bassist Nicolas Thys and American drummer Rick Hollander on the label Acoustic Music Records- he got a lot of recognition for his deep and surprisingly mature playing.

Jason regularly works with trombonist Johannes Herrlich’s Collage, the Bobby Burgess Bigband and the Al Porcino Big Band in Nuremberg. In the last years he has been performing for radio stations all over Europe such as the BR, SDR, VPRO, VARA and Public Radio Station Miami, USA.

His further credits include working together with musicians such as: Benny Bailey, Bobby Burgess, Jiggs Whigham, Dusko Goykovic, Don Menza, Marvin Stamm, the Munich Saxophone Family, Kenny Garrett, Philippe Catherine and Maria Schneider.
