Query: This One Is A Masterpiece:

If I never see another Concert in DVD again, I'll be glad that I picked up this one. This is for people who just love strait-ahead Jazz. The minute I sat down and watched it, I called my friend (J.C) and told him, "don't ask any questions, just go on Amazon.Com and pick this one up, you won't regret this one."Jack DeJohnette, Hancock, Metheny and Holland, put together some pieces here that will send you thru the roof. The Audio Sound is Great, despite it not being DTS. None-the-less, this is a must in your collection. It really does not get any better than this. RIGHT ALONGSIDE "CASINO LIGHTS 99"
