Miles Davis is one of my favorite musicians. In his career he always progressed, from his work in the bebop era with the likes of Charlie Parker and Dizzy Gillespie, to cool jazz, hard bop, modal jazz, electric and more detailed periods in between. Miles never looked back, but in each of these periods, he strived to make great music.
Personally my favorite period in Miles's musical life was his modal jazz period, and the album produced in this period, Kind Of Blue. (Below is a piece, All Blues from that album.)
Miles chose great players such as Julian "Cannonball Adderley on alto saxophone, Paul Chambers on double bass, Jimmy Cobb on drums, John Coltrane on tenor saxophone, and Bill Evans on piano for Kind of Blue. Miles Davis chose great players, with individual, developed sounds, put them together and made one of the greatest albums of all time.
