What set Davis apart (well, one of the things, anyway) was his willingness to chart new waters.

Miles was a good student, but had more important things to do with his time than attend music school) Miles fell in with the great bebop musicians who's style of music was so popular at the time. He played regularly with Coleman Hawkins, Freddie Webster, Thelonious Monk and Dizzy.
After a breakup with Charlie Parker, Davis collaborated with the arranger Gil Evans.
