The album was co-produced by Spalding and longtime David Bowie collaborator Tony Visconti.[1][2] On the album, Spalding sings through the alter ego of Emily, which is her middle name.[3][4] In an interview, Spalding stated that Emily "is a spirit, or a being, or an aspect who I met, or became aware of. I recognize that my job...is to be her arms and ears and voice and body".[5]
Emily's D+Evolution received widespread critical acclaim from contemporary music critics. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the album received an average score of 84, based on 14 reviews, which indicates "universal acclaim".[7]
Marcus J. Moore of Pitchfork Media praised the album, stating, "The lyrics are elusive at first, darting behind fast-moving songs and delivered in impressionistic, conversational bursts that recall the delivery of Joni Mitchell. But the fearless generosity behind them communicates itself loud and clear, and it's a spirit that animates the entire album. With it, Spalding has once again redefined an already singular career, dictating a vision entirely on her own terms".[5] Michael J. Warren of Exclaim! commented, "Emily's D+Evolution is a tough album to get a full grasp on. It's not a neat alter ego side project; rather than going the Chris Gaines route, Esperanza Spalding is again flexing her range, showing that her playing style and voice can find a home in any genre. There are moments here where she falls into a nice pocket that the listener might wish she'd remain in for a little while longer."[9] Christopher R. Weingarten of Rolling Stone added, "...Emily’s D+Evolution is a far more ambitious and thornier affair. The lyrics, flowing in disjunctive clusters, are about deleted narratives, glass ceilings and dreams deferred – ultimately a complex, funky prog-rock concept opera about love and identity.[12]
