Guitarist Henk Zwerver, bassist Raoul van der Weide and percussionist George Hadow, frequent collaborators in the Amsterdam free improv scene, join with Berlin saxophonist & clarinetist Edith Steyer to make up the Bertch Quartet, their debut album a great and embraceable example of subtle, collective free improvisations that merge traditional and non-idiomatic forms.

Recorded live at Zaal 100 in Amsterdam in 2017, the quintet Zwerv — Raoul van der Weide, George Hadow, Henk Zwerver, Ziv Taubenfeld, and Luis Vicente — deliver five dynamic free improv explorations, balancing percussive guitar textures, driving rhythm section interplay, and vivid horn lines that channel both the European free improv tradition and the spirited edge of Dolphy-inspired jazz.
