I believe it's the composer playing his own piece but I don't know.
I've been investigating the composers who have placed or win in the composers competitions of the Boston Guitar Festival. I'm floored by the talent and the extensions of technique and the quality of the music. If it weren't way too late for me I'd start getting to work, besides, I sprained a finger this morning.
Here's another piece by another of those who have shown up in the list but playing another of his compositions.
Nejc Kuhar - Black Hole
I take that back, just noticed this piece did win a prize in an earlier year
