Aboagora 2023: Void
I played cello and designed interactive electronics for a performance and installation made for Aboagora Symposium 2023: Void.

I wrote a piece for orchestra and choir to honor the Forssa 100 years celebrations. The piece was commissioned by Lounais-Hämeen musiikkiopisto and Terhi Karhumäki.
