New Music for Flute and Cello
Together with my dear Anna-Sofia Kallio, we organised a tour playing Finnish and Icelandic music for flute and cello. The concerts were in Turku, Tampere, Helsinki, and Forssa (x2).

Elementtejä Forssasta
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.

Once-musikaali
My acting debut in Turku City Theatre during the season 2024 - 2025 with an amazing group of musicians and actors.
