Agreed, but I'd take exception to your "fifty years ago". As related above, Miles was an important entry point into jazz for me in 1958, which is 63 years ago. For me, it was the 1954 Miles, Monk, Milt, Klook session that was so inspirational, but had we been able to get them, the "Walkin', etc Prestige albums were already there, not to mention Miles Ahead, which I heard on release, and Milestones.
By 1958 I also knew Miles as a Parker sideman, as I owned an LP of the Savoy tracks.
