On Monday 9 June 2025 the TCP/Indeterminate Place quartet performed Reconciliation, a piece we composed in 2024 for a special double duo telematic performance in which two of us performed at the Kapelle der Versöhnung in Berlin and the other two at the Orgelpark in Amsterdam. This time we were all at the Studio Acusticum main concert hall, playing our instruments and interacting with the massive Acusticum/University pipe organ in several ways. I experimented with the pressure aftertouch of the Sophtar as a way of adding and subtracting stops to the registration of the IV manual of the organ. Here is short snippet I recorded with my phone during sound check.
TCP/Indeterminate Place is:
Mattias Petersson: parsimonia, live coding, hyperorgan
Stefan Östersjö: midi electric guitar, hyperorgan
Robert Ek: augmented clarinet, hyperorgan
Federico Visi: sophtar, hyperorgan
Our performance was a prelude Mattias Petersson’s successful PhD defence titled “The Act of Patching” that took place the following day.
