While it is true that some teachers teach what they teach, regardless of what you want, as an already accomplished musician, you should be able to sort the wheat from the chaff--as to blues, GUEST, someone who really plays blues teach you things that most self-taught players *never* figure out on your own--same with the other genres--

I am sure that Khatt will do well, whatever path he chooses, though, if for no other reason than that the formal music background really does help!
