Peter Beets - Fender Rhodes piano - is one of the most virtuoso pianists of the current generation. He is a regular pianist of the JOC and to the last, was a member of the band of Europe's First Lady of Jazz, Rita Reys. His playing is characterized by an untameable fun with great swinging virtuosity.
Martijn van Iterson - Guitar - belongs to the absolute top of the Dutch guitarists, trained by the legendary Wim Overgaauw, graduating cum laude from the Hilversum Conservatory in 1993. He has been a regular partner of Peter Boots for a long time, including Rita Reys. His compositions find their way to many top formations at home and abroad.
Ruud Breuls - Trompet, Flügelhorn - originating from Urmond, Limburg, a breeding ground for many brass players, where he, like his father and brothers, played the trumpet in the local brass band from an early age. He studied both classical- and jazz music at the conservatories of Rotterdam and Hilversum. He was the lead trumpet player for the Metropole Orchestra until his transition to the equally legendary WDR Big Band from Cologne.
Frans van Geest - Bas - was co-founder and is still a member of the JOC. He is a teacher at the Codarts Conservatory in Rotterdam and a much demanded accompanist to an enormous list of great American and European jazz musicians. He regularly played with all kinds of ensembles in Porgy and Bess.
Martijn Vink - Drums - is considered by many to be the best jazz drummer in the Netherlands. He may have played in the more formations than any of other band members. He did play in the JOC, the Brussels Jazz Orchestra, the New Rotterdam Jazz Orchestra, the Ploctones, New Cool Collective, Tineke Postma and so on. For years now he has been the rhythmic beating heart of the Metropole Orchestra, in which he is very emphatically present without really playing hard. He plays on drums from the 60s and 70s, but this time on the drums from Porgy and Bess.
