I wanted to get some thoughts from other members on a couple of instructional DVD's--Trumpet Secrets Revealed, by John Thomas, and Playing Trumpet the James Morrison Way, by (oddly enough) James Morrison. Has anyone watched them, and if so, what did you think? Was the presentation interesting, informative, so-so? I'm always looking for new approaches to teaching, and I thought these DVD's might have some material that might help make certain concepts clearer for students. Thanks in advance!!
