Ocarina player in the movie

The ocarina player made the soundtrack. Haunting. Compelling. Lending so much emotionally to the soundtrack. To me, it was an Oscar-award-winning performance soundtrack, mainly because of the master ocarina player. But he/she isn't identified.

Anyone here know who played so masterfully played the ocarina in the movie, and lended so much to the soundtrack? Unbelieveable. I'd call him/her a virtuoso of the ocarina. A tough but beautiful sounding instrument to master.
