Groove Licence

A Hammond Organ trio which plays exactly the kind of music you would expect: soulful,in the pocket grooves you can dance to.
One of the few Organplayers nowadays that can really swing is Ronald van Driel and having played with Dr.Lonnie smith, I should know! Ben Schröder is the perfect drummer for this Lineup: robust yet sophisticated. Never out of fashion this music keeps bridging the gap between art and entertainment.

Martien Oster – guitar

Guitarist Martien Oster has an impressive track record and has been at the top of the Dutch jazz scene for years. Martien has worked and recorded CDs with the likes of Monty Alexander, Diana Krall and Dr. Lonnie Smith. In 2016, he toured with fusion pioneer Larry Coryell whom Martien describes as an “intelligent and soulful guitarist.” He did his most current CD production with Harold Mabern titled “Handshake.”

Martien’s style of playing is clearly rooted in the Jazz tradition but at the same time he is always looking for adventure. 

Ronald van Driel – organ

Ronald started playing the Hammondorgan at the tender age of 9. Still a young man he played with drummer Ray Appleton who played an important role in the further development of Ronald’s career. Ronald inspired by Jimmy Smith, Larry Young, Jimmy McGriff and the French organplayer Eddy Louiss. Ronald’s formal musical training was with legendary pianoplayers Rob Madna en Rob van Kreeveld.

His swing is intense with an incredible driving force which gives him his licence to Groove!

Ben Schröder – drums

Ben Schröder first learned guitar when he was 7 years old and later switched to drums. First he played Stones and the Beatles untill I fell madly in love with my jazz for example Miles Davis and John Coltrane. Through self study he became one of the most swinging drummers in the Netherlands who played with virtually everybody and was sought after by many visiting international artist.  

Ben is considered the uncrowned King of the original “shuffle”!



In April and May of this year we're planning a Live recording in Budapest after touring in Hungary and Austria.
