Never experienced a lesson from Glenn. But, when I was in medical school, Glenn played at a local restaurant in Greenville, TN. This was in the late 1980's. It was obvious he was well trained and very talented. I remember him telling us that through all his training, it wasn't until his 30's that he started to feel the music and express it accordingly. When he played Claire de Lune it brought us to tears. And we always requested it when we dined there. My wife and I were thinking about him recently and I found him on this site. If he is able to convey a fraction of what he is able to express through his playing to the student, then his lessons would be well worth it.
