Recorded in December 1965 and released 18 months later, this session features a sextet rather than one of Mobley’s usual two-horn bands: frequent collaborator Lee Morgan is on trumpet, joined by trombonist Curtis Fuller, pianist McCoy Tyner, bassist Bob Cranshaw, and drummer Billy Higgins. The title track is a nearly 10-minute workout in the vein of Morgan’s “The Sidewinder,” with each horn stating their piece over a foot-stomping groove. The three other Mobley originals filling out the album are less visceral, but just as much about the whole group sound rather than any one man, even when that man is soloing. They also interpret Wayne Shorter’s “Venus de Mildew,” which Morgan and Higgins also recorded for the trumpeter’s album The Rumproller around the same time.
