[12] The studio tracks were performed by the classic Coltrane quartet (pianist McCoy Tyner, bassist Jimmy Garrison, and drummer Elvin Jones), who are joined by saxophonist Eric Dolphy and bassist Reggie Workman on the tracks recorded live at the Village Vanguard.

[13] Dolphy contributes a long bass clarinet solo on "India", but lays out on all but the final chord of "Impressions".

[14] Workman plays only on "India", joining Garrison in approximating the droning sound of Indian classical music.

"[19] The result was the recording of the single "Eight Miles High", acknowledged by the band as a direct homage to Coltrane, and to "India" on Impressions in particular.
