The best selling jazz album in history, Kind of Blue sounds better with each passing year. Miles explores modal improvisation with pianist Bill Evans, saxophonists John Coltrane and Cannonball Adderley and other top-flight talents. This musical voyage proves that "relaxing" music can also possess incredible depth. This 50th Anniversary edition comes with alternate takes and studio chatter plus an entire disc of other material the group performed together. You can't get any better than this.
