excellent work!
It's a real pleasure to hear live works on NG for a change. Wonderful! Who were the players? They sounded quite professional! The recording quality sounds great, too. Judging by the natural ambience, this was recorded in a large hall...where in Opole, Poland was this recorded? And are those voices near the end?
As for the piece itself, the thematic material was clearly introduced and developed very well throughout the piece. I liked the temporary switch to 6/8 time in the middle; mixed things up a bit. I listened to its entirety and really enjoyed it. Looking forward to hearing more from you!
