One of the few succesful attempts at using a gospel choir on a jazz recording (along with Max Roach's "It's Time" LP from the previous year...which, coincidentally, featured the same chorus), Byrd's "A New Perspective" album was the first time it was really attempted with a small group setting (Roach's was backed by an orchestra). This, the opening track, begins with a vocalese scat by the choir that calls to mind old slave work songs. From there, the incredible band (featuring a very young Herbie Hancock and Kenny Burrell, among others) strikes up, and begins to follow a basic riff with the chorus that takes you through the remaining nine-plus minutes with various tempo changes throughout. An equally impressive edited version appeared as a b-side to the single of "Cristo Redentor", which got to be a minor hit on the pop charts.
