About Us

Astria Oboe Trio was founded by Yf Bourry in 2009. Eric Speller and Dimitri Mestdag joined from the very beginning. They have been seeking creative arrangements and cross-overs from the outset, including theatre and video art. Contemporary music is quite often composed for them on such occasions. They have performed on international stages in France, Bulgary, Estonia and China.

With Korneel Alsteens embarking in 2020 Astria Oboe Trio expanded towards a broader artists collective.
