Digitally remastered edition. Butterfly is the sixth studio album by Mariah Carey, originally released on September 16, 1997. The album contained both hip hop and urban adult contemporary sounds, as well as some softer and more contemporary melodies. Throughout the project, Carey worked with Walter Afanasieff, with whom she had written and produced most of the material from her previous albums. She also worked with many famed hip hop producers and rappers, such as Sean "Puffy" Combs, Q-Tip, Missy Elliott and the Trackmasters. With the latter acts producing most of the album, Butterfly deviated from the contemporary sound of Carey's older work.
