A John Coltrane owned and stage played Yamaha prototype alto saxophone, presented to him in Japan by Yamaha. Coltrane played this horn extensively on his two week Japanese tour, and was both photographed and recorded playing it. It was also pictured in Coltrane's home studio in the Japanese publication "Swing Journal." Impeccable provenance as it came directly from Coltrane's estate. A treasure I am proud to have owned.
