Iconic saxophonists John Coltrane and Eric Dolphy are captured together in a never-before-heard recording from the summer of 1961.

Evenings at the Village Gate: John Coltrane with Eric Dolphy was recorded at the celebrated Village Gate jazz club in New York, with Coltrane performing with a short-lived quintet of Dolphy, pianist McCoy Tyner, bassist Reggie Workman, and drummer Elvin Jones.
