When the album came out, Billboard predicted, "This should be Mathis's biggest release in years,"[15] and that his "vocals are characteristically effortless as he glides over the big orchestral arrangements by Gene Page."[15] They also like the variety of genres covered. "The diversity of the material challenges him as a singer to make this one of his most well-balanced and fully satisfying albums."[15]
