Zwerv
Zwerv is an Amsterdam-centred improvising ensemble whose recordings include Henk Zwerver, Raoul van der Weide, George Hadow, Ziv Taubenfeld and Luís Vicente, with additional players on selected releases.
Live (CS433) documents a quintet, while Music from Any Moment (CS530) expands the instrumentation with trombonist Salvoandrea Lucifero and pianist Nico Chientaroli. Both albums were recorded at Zaal 100 in Amsterdam.
