"Pianist Marta Warelis (1986) is a vibrant performer with a strong preference for improvisation and experimentation in all genres. She continually aims for instant composing on the basis of new sounds and influences. Her work draws inspiration from music across the globe including cumbia, Angolan dance music, as well as jazz, western classical music and the various schools of free improvisation. Born and raised in Poland where she graduated with honours from WSJiMR in Wroclaw, Marta moved to Groningen in 2010 to attend the Prins Claus Conservatory. In 2014 she found her place in Amsterdam, very quickly becoming an active member of the local improvisers' scene. Marta has appeared frequently in the Bimhuis, where in 2017 she was given a Carte Blanche in recognition of her remarkable talents. She performs with a variety of creative musicians including Michael Moore, Ab Baars, Mike Reed, Andy Moor, Joost Buis, dancers Lily Kiara and Michael Shumacher, as well with such groups as Hupata!, Omawi, Future Neighbor, Polyband, Edge Ensemble, Strings5, Xavier Pamplona, Warelis/Rosaly/Lumley/Dikeman and Bazooka."

Onno Govaert is a drumer from Amsterdamn performing free jazz, swing and rock. He is a member of Cactus Truck with Jasper Stadhouders and Wilbert de Joode, and has also recorded with Andy Moor, Colin McLean, and John Dikeman, and with Dave Rempis and Frank Rosaly.

"Wilbert de Joode (1955) is a veritable research scientist of bass pizzicato and bowing techniques. A self-taught musician, he has been playing the double-bass since 1982. He began working in groups that improvised within a jazz framework. Other musicians were soon drawn to his idiosyncratic style, and in the mid 80s he played in groups led by Vera Vingerhoeds, Armando Cairo and Ig Henneman where he further developed his improvisation skills. He came into contact with such musicians as J.C.Tans, Rinus Groeneveld, Michiel Braam, Han Bennink, Han Buhrs (Schismatics) and Ab Baars.

De Joode is currently one of the most active bass players on the European improvised music circuit. His individual style and musicality transforms the double bass into an equal partner in the most varied ensembles. A personal tone colour, exploration of the outer registers, quirky improvisations and the use of gut strings contribute to an instantly recognizable and intriguing sound.

The seventeen improvised pieces on his first solo cd Olo (distributed by ToonDist) show how rich and complex his sound on the double bass is."
