The album was produced by EWF leader Maurice White. When asked about his favorite non–Earth, Wind & Fire album, White replied: "The Emotions's Rejoice because it had a great vibe, a great ‘feel’. Yeah, I'm proud of that production."[3]
Ace Adams of the New York Daily News stated that the album "displays the growing talent of these rising stars."[8]People said: "This LP offers no messages, pretensions or sexual innuendos but simple romantic themes by four sisters, Wanda, Sheila, Pamela and Jeanette Hutchinson. Their tight harmonies and polished chords make them logical successors to the original Supremes. Producer Maurice White of Earth, Wind and Fire (with whom the girls have toured) provides lush arrangements and joins lead singer Wanda in a smoothly worked Key to My Heart."[9]Larry Rohter of The Washington Post wrote: "As much because of their material as the(ir) vocal style, the Emotions have been able to inject some life and excitement into a soul format that badly needed it."[10] Phyl Garland of Stereo Review proclaimed: "Though there is nothing here that is truly new in terms of musical format or content, "Rejoice" demonstrates what can be done within the limits of popular style when talent and imagination are applied." Garland described the girl group's performance as "thrice nice" and called Rejoice a "very good" album.[11]Robert Hilburn of the Los Angeles Times commented: "Produced by Earth, Wind & Fire's Maurice White, the album has material that is ideal for the female vocal trio's mostly light, upbeat style. The arrangements, too, are skillfully tailored. Not much adventure here, but solid craftsmanship. That ought to count for something these days."[12]
Craig Lytle of AllMusic found that "the radiance the Emotions impart is heartwarming and uplifting... Their gospel roots bring a welcome spiritual feel to this album, which is a superb effort."[5]
