James Holden and Wacław Zimpel met in the summer of 2018, by improvising in the London studio of the first one. Loving musical hypnosis and trance, the duo will present an unexpected set based on improvised partch synthesizers of the alto clarinet with the colors of the modular authors. The trance, whose music oscillates around the duo, preserves the form of traditional folk, 20th-century minimalism, electronic dance music and improvised jazz. The concert will be audiovisual.
