Six chamber works for strings by Korean composer and Fluxus performance artist Kunsu Shim, performed by the Luna String Quartet, "specialists in quiet music", along with six short pieces written for Kunsu by composer friends and collaborators, including Arnold Marinissen, Ammon Wolman, Alwynne Pritchard, Nicolaus A. Huber, Gerhard Stabler and Anton Lukoszeviez

Antoine Beuger, Burkhard Schlothauer, Chico Mello, Jurg Frey, Kunsu Shim, Michael Pisaro-Liu, and Thomas Stiegler participate in this realization of Christian Wolff's compositions to make sounds or draw sounds out of stones, alone or with other surfaces, acoustically or amplified.
