Miles Davis' Kind Of Blue is a landmark album, introducing a style known as cool jazz. It is easy to see where the name comes from as the songs have an icy air of coolness to them. "So What" is an utter masterpiece and contains the amazing dual sax work of two legends in their own right, John Coltrane & Cannonball Adderly. As good as those two gentlemen are, it is Mr. Davis' album and he is in clear command on that track and on "Freddy The Freeloader" he has a laid back, yet forceful sound that shows why he is a true genius.
