Mongrain is an amazing guitarist. I've seen a couple vids of his and he blows me away. Makes me want to sell my guitars too.
A few months ago, a friend of mine convinced me to go to a concert with four acoustic guitarists. One of them happened to be Don Ross. If you're a fan of acoustic guitar, check this out: http://www.youtube.com/watch?v=ip111lXjDSs
He played this song that night as well. Blew me away.
