It was so exciting to hear it! To be honest, I was pretty nervous, because I did not want to hear mistakes, whoops. The premiere was in an old house in Amsterdam and I found the acoustics much more suited for my piece. It turns out that the hall in the Vredeburg was a Jazz hall for electronic music. Acoustic music sounds too plain in my opinion.
Nevertheless, I am very happy!
The Keuris Quartet is one of the best (known) saxophone quartets in the world. They won many international rewards and they are of the highest level one can have. Their speciality is contemporary music, so you have heard that correctly!
