French composer Mark Andre's ...auf... consists of three independent orchestral pieces. Taken together, they can be heard as a cycle or as a triptych. Though they are related, each work begins again the search for new resonances and means for transitions between sounds. Andre studied composition with Claude Ballif and Gérard Grisey at the Conservatoire de Paris. He continued his studies in Stuttgart with André Richard at the SWR Experimentalstudio and with Helmut Lachenmann.
