Composed of four parts, each has a thematic progression leading to an understanding of spirituality through meditation. From the beginning, "Acknowledgement" is the awakening of sorts that trails off to the famous chanting of the theme at the end, which yields to the second act, "Resolution," an amazingly beautiful piece about the fury of dedication to a new path of understanding. "Persuance" is a search for that understanding, and "Psalm" is the enlightenment. Although he is at times aggressive and atonal, this isn't Trane at his most adventurous (pretty much everything recorded from here on out progressively becomes much more free, and live recordings from this period are extremely spirited), but it certainly is his best attempt at the realization of concept — as the spiritual journey is made amazingly clear.
