Guitarist Henk Zwerver leads this collective free improvising band in their second release, now extended to a septet with the addition of Salvoandrea Lucifero on trombone, joining Zwerver: Ziv Taubenfeld on bass clarinet, Luis Vicente on trumpet, Nico Chientaroli on piano, Raoul ven der Weide on double bass, objects, and George Hadow on drums.

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.
