Giannis (xShark7x) is very well known by amateur bouzouki player who are learning from internet. He has a great Youtube channel and he started making Backing Tracks for free on his website: http://www.kotsou.com . If you want a Backing Track that he hasn't done yet, you can go on his website and request it, and you will get in in the shortest time possible. Thanks a lot Shark for your work!!
