Yes, pertinent info, he puts it in excellent context of why it is important. It is obvious how it will make you a better player. I especially like the talk at the begining about purposeful practice. I needed that.
Since I dont play in a band anymore, I do loose much of the theoretecal knowledge that I had. It is good to review this. My worry is that after the course I won't have application for this and will forget it again. I usually play a repertoire of fingerstyle pieces but would like to mantain the knowledge that I am learnig. Hope has techniques for that.
