Background: Marshall Bruce Mathers III (born October 17, 1972), known professionally as Eminem (often stylized as EMIN3M), is an American rapper, songwriter, record producer, record executive, and actor. Eminem is the best-selling artist of the 2000s in the United States. Throughout his career, he has had 10 number-one albums on the Billboard 200 and five number-one singles on the Billboard Hot 100. With 47.4 million albums sold in the US and 220 million records globally, he is among the world's best-selling artists of all time.
Context: In February 2017, Eminem appeared on "No Favors", a track from Big Sean's album I Decided. In the song, Eminem calls the newly elected President Donald Trump a "bitch", and also raps about raping conservative social and political commentator Ann Coulter, who is a Trump supporter, with a variety of foreign objects. Coulter responded to the lyrics, stating, "I think it's unfortunate that the left, from Berkeley to Eminem with his rap songs, has normalized violence against women, as Eminem has done." Eminem participated in the 2017 BET Hip Hop Awards' annual cypher, using his verse, a freestyle rap called "The Storm", to further criticize Trump and the administration for, among other things, Trump's focus on National Football League players' protests during "The Star Spangled Banner" over Hurricane Maria recovery efforts and lack of gun control reform in the wake of the 2017 Las Vegas shooting. Eminem ended the cypher by giving an ultimatum saying that Trump supporters cannot be his fans. The verse received wide praise among other rappers following its release. In October 2017, Eminem appeared on "Revenge", a track from Pink's album Beautiful Trauma.  Starting in late October, Eminem and Paul Rosenberg began teasing what fans speculated was the title of a new album titled Revival, in the form of advertisements for a fake medication of the same name. Later in November, the first single "Walk on Water" was released, which featured Beyonce. The song was first performed, by Eminem, at the 2017 MTV Europe Music Awards on November 12, featuring Skylar Grey. He appeared on Saturday Night Live on November 18, performing "Walk on Water", "Stan" and "Love the Way You Lie" with Skylar Grey. On November 28, Dr. Dre posted a video confirming the album's release date as December 15, 2017. On December 8, Eminem released a promotional single titled "Untouchable" which featured a sample from the duo Cheech & Chong. Despite an online leak of the album two days prior, Revival was released as planned on December 15. On January 5, 2018, the second single "River" was released, which featured Ed Sheeran. It became Eminem's eighth consecutive album to top the US Billboard 200 upon release with 197,000 copies sold in its first week. As a result, he became the first musical act to have eight entries in a row debut atop the chart. The album was met with mixed reviews from music critics.  In 2018, an extended edition of "Nowhere Fast" with Kehlani and a remix of "Chloraseptic" featuring 2 Chainz and Phresher were released from Revival.
