Lorenz_1 - I studied some of his music. In fact, his book is a great book to read about musicians/ and their life on the road. As you know, Miles died poor. In fact, he'd borrow someone's horn while sitting in on jam sessions. Unfortunately, his drug habit caused him to sale his trumpets to support his habits.
He used alot of spacing in his playing. BB (a curse) is famous for this style of playing. As for a great example of spacing, check out Miles Live in Montreal (Jazz Festival). At one point, he stop playing and walks of the stage (unannounced) and leave the musicians out there for 30 minutes. Then, he walks back to the mic, end the song and walks off again. He was the MAN.
