Yep. I remember you and I having a PM conversation (years ago) about Jeff. I saw right away that you were the guy who was going to "get it" eventually, and you very quickly did. The essence of the problem was that Mr. Berlin's communication style tended to detract from his message, which was and remains *incedibly* important for anyone who wants to make their living playing music. That is, there is a difference between academic learning and art, and the most efficient and complete way to learn music is to momentarily forget about art (groove, feel, "soul" LOL), focus on academics, make LOTS of mistakes, stop and correct them, and once the academic lesson is absorbed, THEN go use it in an artistic way.
Berlin reminds me a lot of my High School's old music teacher. He was no-nonsense, old-school, strongly focused on academics, and a bit abrasive. But his methods worked. Once he came on board, the band sounded better than it had in years, and wasn't the same after he left. I don't argue against the merit of a given approach when the results are so crystal clear.
I hope that Jeff is making real, sincere progress on his personal issues, both for his own happiness and the importance of his message. It needs to be heard and absorbed. It takes a lot of balls to publicly apologize for one's actions and admit a personal fault. I hope this personal turn takes hold.
