I was driving home late one night and this extraordinary, experimental jazz piece comes on the air (KUVO, Denver). I was captivated and my daughter who was with me correctly identified the instrument as the bass clarinet which she had played in her middle school orchestra. I later found out it was Eric Dolphy - God Bless The Child. I hope you have a chance to listen to it: https://www.youtube.com/watch?v=xQZ1c3ixoa4
