"This strange novel-parable launched Cover’s long SF career in 1975. A repulsive demon, a black-derbyed lawyer, and a white-suited fat man plot to bring morbid depression to their race of godlike men, giving them purpose to master the universe. Their instrument is a pathetic crawling bird, whose heart-aching song of lament at its inability to fly causes listeners to feel anger and disappointment. Out of this quirky start, Cover swirls a phantasmagoric slew of allusions, quasi-references, and escapist "sampling" into something Harlan Ellison’s introduction calls "entertainingly meaningful."
