The CD release added tracks from a 1966 session featuring Hosea Taylor, Herbie Hancock, Reggie Workman, and Elvin Jones.
Allmusic reviewer Scott Yanow stated: "The set is comprised of seven diverse Hubbard originals and, even though none of the songs caught on to become standards, the music is quite challenging and fairly memorable."
As stated in the liner notes, "The use of a fourth horn for this album, coupled with an exclusive focus on Hubbard's compositions, really threw light on the trumpeter's command of harmony, which is such a critical part of both his improvising and writing personality".
[5] Hubbard's playing here is among his best, and this album "is arguably the best recorded example of the Hubbard/James Spaulding partnership"[6] which had been ongoing for the previous two years.
