I was handed Kind of Blue and was told, "this will cd will change your life". I'm a die hard Louis Armstrong, Bix Beiderbeck, etc. fan, but I couldn't grow to like this album.I thought maybe I needed to listen to the cd for a couple times to even begin to understand its sophistication or importance, but finally I gave up, and said this is not for me.I am not meaning to diminish the quality of this cd, for it appears that many hold it up high, but for me it was less than adequate.
