Edition ZKM is dedicated to productions from the ZKM-Institute for Music and Acoustics. The institute is part of the Center for Art and Media Karlsruhe, Germany, (ZKM) which also includes the Museum for Contemporary Art, the Media Museum, a Media Library and the Institute for Visual Media. Guest artists from all over the world are invited to work in the music studios to realize specific projects. The projects, ranging from digital synthesis and algorithmic composition to the integration of live electronics, from radio art to sound installation, encompass a broad spectrum of that locus where digital technology stimulates musical fantasy. In his composition "Etude d'aprés Seraphin", Rihm works intensively with digital electronic means for the first time. As a layer of commemoration (also of pre-civilization sound levels) the electronic part is closely connected with the eleven live playing instrumentalists. Since their first performance - 25 years ago - Ensemble 13 has been praised for their perfect interpretations of contemporary music. This production received the quarterly German Record Critics' Award.
