have examined methods in which we can integrate improvisation concepts
(i.e. Vinko Globokar's Individum/Collectivum, Karlheinz Stockhausen's
Improvisationen anregungen, Bryn Harrison's Texts for Improvisation,
and our own self-developed concepts) into our concerts. The use of
improvisation is something that our duo has always been interested in-
it challenges our perceptions of aesthetics, develops both sound and
instrumental techniques, and creates a sense of true 'ensemble'.
Although we have taken a break from 'sundays at five', we had been
improvising every Sunday from 5pm until 6pm in our rehearsal space in
the Lagerhausstraße and then in the Kronenmattenstraße in Freiburg.
This hour was the only constraint given, leaving everything else free.
Our last improvisation project was with composer-improviser, Thomas
Wenk (electric piano/Sketcher)- Schwarzweiss, which used live video of
his drawings as a catalyst and also a sound producing instrument. This
was performed at the Elisabeth-Scheider-Stiftung in Freiburg and at the
Radbrunnen in Breisach, Germany.
