2023 reissue as part of the Blue Note Tone Poets Series, originally released in 1967 - features the great trumpeter in three challenging settings ranging from a sextet to an octet. Hubbard uses such sidemen as altoist James Spaulding, tenors Joe Henderson and Hank Mobley, the euphonium of Kiane Zawadi, pianists Harold Mabern, McCoy Tyner and Herbie Hancock, bassists Larry Ridley, Bob Cranshaw and Reggie Workman, drummers Clifford Jarvis, Pete La Roca and Elvin Jones, the congas of Big Black and on one song bassoonist Hosea Taylor. The set is comprised of five diverse Hubbard originals and, even though none of the songs caught on to become standards, the music is quite challenging and fairly memorable.
