Coltrane improvisation

"This improvisation is based on John Coltrane's tune 'Vigil,' a drum-and-saxophone duet that he recorded with Elvin Jones on June 28th, 1965, a little more than a month before this performance. Trane plays the 'Vigil' melody within the first few moments of the beginning of this, returns to it several times during the solo, and plays some of the same ideas during this improv as what he played during the 'Vigil' recording.

"'Vigil' first was released on the album Kulu Se Mama and now is collected in The Classic Quartet: The Complete Impulse! Studio Recordings."
