Rinus Groeneveld

Rinus Groeneveld (a.k.a. Sunirae) started with flute and tenor sax and played with Hans Dulfer & De Perikels, Dexter Gordon, Tete Montulio, Big Jay McNeely and De Bluesbastards, among others. Over the years he performed in - and leaded - various funky, poppy jazz and blues formations. Rinus is known for his unique warm blowing technique and occasional fat 'ripping' sound.

Rinus comes from a large family and his brothers and sisters brought him all kinds of records. From Fats Domino, Ella Fitzgerald and Ray Charles to The Four Seasons and Mozart. One of the reasons he is always willing (even hungry) to try everything.

Rinus also has his own analog studio, where he records many bands and artists. And in 2024, he published an impressive book, Tenoritus, about living with the condition tinnitus. He describes the great impact it has on his life, but especially how resourcefully he deals with it.

Eric Barkman

Eric Barkman is a bass player in body and soul, known for his solid beat and energetic appearance on stage. After years of playing the piano and saxophone, he taught himself to play the bass.

At home in many music styles, preferably playing the bass guitar and electric double bass (stick bass), he has been the regular bass player for more than 20 years of top saxophonist Hans Dulfer. Eric also made several CDs and performed with other many renowned musicians, such as Benny Wallace, Ingram Washington and Joseph Bowie (Defunkt).

With Greenfield Inc. Eric can do what he likes the most: all kinds of music styles, unexpected songs and groovy bass effects.

Martien Oster

Martien plays the classical guitar since he was 11 years old. Influenced by rock/blues, the music of that era, the electric guitar soon followed. His switch to jazz eventually was heavily influenced by his brother-in-law, a well-known record producer, who showed him many great jazz recordings. Jazz allows him the freedom to develop a personal style within a community where everyone speaks the same language.

Martien performed and recorded with Monty Alexander, Red Holloway, Diana Krall, Dr. Lonnie Smith and Larry Coryell.

His style of playing is clearly rooted in the Jazz tradition but at the same time he is always looking for adventure!
