"On August 26, 1965, we find John Coltrane and his quartet recording at RCA Victor Studios on 24th Street in Manhattan. In the tunes tracked for Sun Ship, we hear Coltrane revisiting ground he had covered in the past with heightened sensitivity and a deepened interest in timbre. Sun Ship is a portrait of Coltrane’s most important band during his most important year, and while it’s sometimes overlooked in Coltrane’s discography — probably because it was released posthumously — it’s a crucial document for understanding what this band had accomplished, and it also offers a glimpse of why Coltrane moved beyond it. He needed to be in places where he was less sure of himself."
