To be honest, Im not a big fan of his DVD's. The first one, he just shows you a few progressions and watnot, but I just think it could have been better. And sometimes when he plays, I look and Im like "i wanna do that", but he doesnt necessarily explain what I want to do. Basically, he doesnt explain everything, as if you already know most of it. He may add lil tricks, but not explain everything. And its just not set up the best. Maybe its because Im so used to Jermaines dvds, but Jamals dvds could be better. And for $100 for his second dvd, I would be expecting a lot and I dont think he'll give me enough for $100. But i'll admit, a few of his chapters, I liked. But like I said, he'll teach you a progression you can do in Eb or Ab or whatever, a lil progression thats done at the end of a song. But what if you dont even know how to play in Eb or Ab, then it becomes sorta pointless.
If the price was lower, I may think bout his second dvd, but for $100, I dont even bother thinking about it. Its prolly a good dvd for someone whos been playing for a long time. Both dvds seem to be for people who know a lot and been playin for years.
