At a Dead show many moons ago I saw Mickey Hart play some pieces of what MC is speaking to. And agree that at first it is amelodic and then (given the always incredible sound system) it begins to grow on you and ends up quite fascinating.
The flip side is I saw Steely Dan this past weekend in Boston and they are the best I've heard them play in a few years. Flat out kickin' butt.
Life is too fleeting to listen to music you find distasteful. Although I would never tell anyone what they should listen to. Your system, your ears, your time.
