The Lord sees that the stock value of "Pair-o-dice" is dropping on the exchange so he dispatches a slow-witted and slow-talking angel to sinful Harlem to recruit new customers. When this fails, God finds success sending a group of musical angels with a little more swing in their style, so much so that even the Devil wants to join up!
- The cartoon is a parody of Warner Bros.' 1936 film, The Green Pastures.
- Schlesinger and Warner Bros. had problems with the cartoon from the start. Hollywood censors alleged that the film ran afoul of the Hays Production Code because it burlesqued religion. Later commentators surmise that the censors also objected to the portrayal of a Heaven run by African Americans. As such, the short's stereotypical portrayal of black characters prompted United Artists to withhold it from United States television in 1968, adding it to a collection known as the infamous Censored Eleven.
- Modern critics have been no kinder to the short and cite its portrayal of black characters as offensive and reliant on negative stereotypes.
- Musicologist Daniel Goldmark interprets the film as a send-up of black religion and culture and the increasing identification of 1930s white audiences of jazz music with black culture.[citation needed|date=]
- Religion scholar Judith Weisenfeld sees "Clean Pastures" as a metaphor for the replacement of rural, minstrel show stereotypes of blacks for modern, urban ones.[citation needed|date=]
