Swart Waling Koolhaas is the new album by jazz pianist Joost Swart, drummer Bjorn Waling and producer Jesse Koolhaas. The music is the result of a two-day session where improvisations were recorded and several well-known guest musicians from the Dutch Jazz scene were invited, like Reinier Baas, Joris Roelofs and Jeroen Vierdag. The recorded improvisations on grand piano, drums, and other instruments, combined with the sounds from Jesse Koolhaas’ vintage synthesizer collection fuses into a type of music you can’t really put your finger on. Straight forward jazz, or electronic music. It is both and neither.
