The Vortex-compositions by composer Alex Buess, from Basel, are tailor-made for the three core musicians and founding members of the Ensemble Phoenix Basel: Jürg Henneberger, Christoph Bösch und Daniel Buess. The three interpreters are expanded through amplification to create a sound-physicality together with a pre-recorded tape. Parmegiani's tape composition De Natura Sonorum is THE masterpiece of the so-called acousmatic music using both the raw material of "musique concrète" as well as electronically processed and distorted instrumental sounds.
