What are your thoughts on this? Say you come across a guy who writes great lessons, with all the theory correct, and he also appears to know how to do everything the 'right' way, so to speak... But then you hear his music, and it's the most tasteless, boring drivel you've ever encountered. It happened, and I'm torn about how to view it. The lessons are still great, but I now hear how he applies his knowledge musically, and it's anything but impressive. Is he still a great teacher?
