Milestones, you're in for a treat. Coltrane's Prestiges are a fascinating trip, or trips -- each record is a journey in itself. Later recordings, after mid-1957, are about the height of his sheets-of-sound period (Traneing In, Soultrane). Coltrane made a great sideman, too, with Miles, Ammons, Dameron, etc. The Monk quartets with Coltrane and the two Wilbur Hardens on Savoy are more great music from the same period.
