Some context: D'Angelo was born Michael Eugene Archer, in Richmond, Virginia on February 11, 1974, to a Pentecostal preacher father. He was raised in an entirely Pentecostal family. Archer's musical talents were discovered very early on. At 3, he was spotted by his 10-year-old brother Luther, playing the house piano.
D'Angelo released his third studio album, Black Messiah in December 2014, D'Angelo originally wanted to release Black Messiah in 2015, but the controversial decisions in the Ferguson and Eric Garner cases inspired him to release it earlier. On December 12, 2014, Kevin Liles, D'Angelo's manager, shared a 15-second teaser of the album on YouTube. Two days later, the track "Sugah Daddy", which had been part of D'Angelo's set list since 2012, premiered at 3 am EST and 1,000 downloads were available on Red Bull's 20 Before 15 website. After an exclusive listening party in New York, Black Messiah was released digitally on December 15 through iTunes, Google Play Music, and Spotify. The album's unexpected release was compared to Beyonce's self-titled release in 2013. On January 13, 2015, "Really Love" was released to urban adult contemporary radio in the US.  The album was met with universal acclaim from critics and it currently has a 95/100 mean score on review aggregator Metacritic.

Black Messiah, Beyonce's self-titled album (2013), Run the Jewels' Run the Jewels 2 (2014), and Kendrick Lamar's To Pimp a Butterfly (2015) were noted as laying the groundwork down for the political charged releases that happened in 2016, which included Rihanna's Anti, Kanye West's The Life of Pablo, and Beyonce's "Formation".  D'Angelo performed Prince's "Sometimes it Snows in April" on The Tonight Show Starring Jimmy Fallon in April 2016 accompanied by Maya Rudolph and Gretchen Lieberum as a tribute to the late musician, appearing 'overcome with emotion' at the passing of a major influence.
