Hello!
The Westmorland Youth Orchestra in the North of England performed my new double concerto in November, and if you go onto this website http://www.wyo.org.uk/recordings you can listen to it.
It can be played by students and is set for full Symphony Orchestra, but can easily be transcribed for just strings. The students in the recording are between 12 and 18 years old.
Let me know if you would like to have a closer look at the score.
All the best
Fredrik
