Portuguese violinist Carlos “Zíngaro” is committed to reinventing chamber music through improvisation. He is specially interested in the string group format and in collectives with a solid string presence. In the Spectrum String Trio, we find him in the company of the French hurdy-gurdy player Domique Regeff and the Dutch contrabassist Wilbert DeJoode. This music is somewhere between the worlds of avant-jazz and contemporary classical music, with reminiscences of folk troubadour songs; after all, the hurdy-gurdy has medieval origins. Zíngaro’s sound world is an original one, coming from on one side, Paganini, Shostakovich, and Bartok, and on the other, Stuff Smith, Leroy Jenkins and, Ornette Coleman, whose “bad” violin playing constitutes for Zíngaro an example of how to fight academic virtuosic perfectionism.
