Evolving after a gig in 1963, saxophonist John Tchicai and trombonist Roswell Rudd developed the NYAQ from loft sessions, adding the creative drumming of Milford Graves and bassist Lewis Worrell; ESP was so impressed that they recorded their 1st 1965 album with an Amira Baraka recitation on one track; Reggie Workman then took over the bass chair for their subsequent Mohawk album on the Fontana label.

Recorded during an extended stay at the Half Note in NYC from saxophonist John Coltrane's Quartet with pianist McCoy Tyner, double bassist Jimmy Garrison and drummer Elvin Jones, originally recorded for radio broadcast, here reissued and resequenced to demonstrate Coltrane's evolution in presentation & performance, while also mapping a future to his music.

Two quartets performing two live concerts from 1963 led by John Coltrane on tenor & soprano saxophones, the first at the Newport Jazz Festival with McCoy Tyner on piano, Jimmy Garrison on double bass and Roy Haynes on drums, the second at Birdland with Elvin Jones on the drums, plus 2 studio recordings with that quartet at Van Gelder Studio in the same year.

Bassist Ingebrigt Haker-Flaten is joined by key improvisers Joe McPhee (sax), Joe Morris (guitar) and Nate Wooley (trumpet) for this improvised studio recording, free improvisation with the influence of swing and blues.
