On this excellent set, McCoy Tyner had the opportunity for the first time to head a larger group.
His nonet is an all-star aggregation comprised of trumpeter Lee Morgan, trombonist Julian Priester, altoist James Spaulding, Bennie Maupin on tenor, Bob Northern on French horn, Howard Johnson on tuba, bassist Herbie Lewis, and drummer Joe Chambers in addition to the pianist/leader.
Tyner debuted six of his originals, and although none became standards (perhaps the best known are "The High Priest" and "All My Yesterdays"), the music is quite colorful and advanced for the period.
Well worth investigating.
