Yes. But what if Miles had not hired Wayne and kept George until the end of his acoustic period. Then I imagine that we would be talking about this as the great Second Quartet and a peak period for Miles.
I listen to the quartet with George Coleman a lot. First, Miles trumpet playing was consistently very strong at this time, preceding the increase in physical ailments that inflicted him after 65. Second, the impact of Tony Williams on the music was still very new and fresh, which clearly inspired Miles. On balance, I would say that a lot of Miles' greatest recorded trumpet playing was done with the quartet with George Coleman.
