A seeming contradiction in terms, the unison voices and divergent polyphony that emerges best describes the subtle interactions between these two Swiss reed players--Markus Eichenberger on clarinet and Christoph Gallio (Day & Taxi) on soprano and C-Melody saxophones--their "harmony of coherence" strategies guiding their melodic interlacing and fragmentation.

With "fragments of alien melodies, bizarre call-and-response activities, boiling liquids, airy perturbations, clusters", the electroacoustic improvising quartet of Markus Eichenberger on clarinet, Carl Ludwig Hubsch on tuba, Etienne Nillesen on extended snare drum and Philip Zoubek on synthesizer, focus their listeners on their remarkably turbulent and rich interactions.
