Thanks for the replies guys! Buckwheat Zydeco is great indeed I like very much his interpretation of "Hey Joe".
Sharon Shannon is also incredible in the movie that monellia posted, please let me know if you have some intersting Seamus Begley videos also.
Valfar of Windir a leader of black metal band was an accordion master! Well this is what I'm actually looking for. Some modern music incorporating accordion sounds. Too bad he is dead.
I was looking to Arcade Fire band which is great, but their accordion sound is not very impressive.
Sorry i cannot include Arcade Fire "Rebellion" movie here because i don't have 15 post yet!
So post if you know some other guys who are worth mention for.
