Query: if you need a reason to buy this...

Forget that Davis is one of the greatest musicians of any era. Forget that this is six discs of great music. Forget it all. If you need one reason to buy this set, it is the track titled "Circle In The Round." At 33 minutes long, it is a whirlwind musical epic. However cheesy that sounds, those terms are all I can come up with, and they hardly do it justice. For its scope and power, "Circle In The Round" ranks right next Coltrane's circa 25 minute take of "My Favorite Things" on the Last Giant album. At first, you might think that you'll never get through a 33 minute jazz tune, but you'll listen to it again and again, and you will never cease to be amazed.
