The first album that launched their career, the trio of Jon Hendricks, Dave Lambert and the English Annie Ross pioneered the use of voices patterned on instrumental parts. The daring of this group creates a giddy excitement, which can be heard on tracks such as "It's Sand, Man," whereby the three voices (accompanied by piano, bass and drums) gain altitude in a series of ascending patterns that thrill the senses. Though Ross in particular possesses a fine voice, the attraction is not in the prettiness of the sound as much as the interplay of the voices, and the utter originality of their interpretations. Every song is enchanting.
