No. 1 In Heaven (1978)

"It may not have been the most natural match in music history, but the marriage of Sparks' focus on oddball pop songs to the driving disco-trance of Giorgio Moroder produced the duo's best album in years. From the chart hits "Number One Song in Heaven" and "Beat The Clock" to solid album tracks like "La Dolce Vita," the album surprises by succeeding on an artistic and commercial level despite the fact that neither the Mael brothers nor Moroder tempered their respective idiosyncrasies for the project. Moroder's production is just as dizzying, chunky, and completely rhythm-driven as on his best work with Donna Summer, and the Mael brothers prove on "Tryouts for the Human Race" and "Academy Award Performance" that their bizarre songwriting wasn't compromised."
