What is "wandelweiser"

The Wandelweiser Group is an international group of composers/ performers. It was founded in 1992 by Dutch-born flautist Antoine Beuger and German violinist Burkhard Schlothauer. In 1993 Swiss clarinetist Jürg Frey was invited to join, followed by American guitarist Michael Pisaro, Swiss pianist Manfred Werder, then Austrian trombonist Radu Malfatti the following year, then American trombonist Craig Shepard, and others.

The group runs its own publishing operation, Edition Wandelweiser, and its own record label Wandelweiser Records. According to Radu Malfatti, Wandelweiser music is about "the evaluation and integration of silence(s) rather than an ongoing carpet of never-ending sounds." John Cage is a figure of central importance to the Wandelweiser composers; their music is often referred to as "silent music," taking as its starting point Cage’s work 4'33", the first composition to consist largely of silence, after the "Marche Funebre" by the Frenchman Alphonse Allais.
