Eminem (born Marshall Bruce Mathers III on October 17, 1972) is an American rapper, and both a Grammy and Oscar-winner. He is of mostly Scottish-American descent, and currently lives in suburban Detroit. Discovered by rapper/producer Dr. Dre, Eminem is known as one of the most skillful and controversial rappers in the industry, becoming a crossover sensation with his debut single "My Name Is" while simultaneously earning respect from the hip-hop community for his lyrical talent. He is noted for his ability to change his own verbal pace (flow) and style multiple times within one song without losing the beat, and has been praised for his skill in alliteration and assonance.

He is infamous for the controversy surrounding many of his lyrics. With the enormous success of his sophomore album The Marshall Mathers LP following its release in May 2000, and its subsequent nomination for four Grammy awards including Album of the Year, critics such as GLAAD denounced his lyrics as homophobic, while others complained that it was also extremely misogynistic and violent. However, he has received a great deal of praise within the hip-hop community for his lyrical ability. He is the second-highest selling rapper of all time, behind Tupac Shakur, though the latter has had several posthumous albums released.

While generally avoiding overtly political tones previously (or if they were mentioned it was in passing), in late 2004 before the presidential election, Eminem released the song "Mosh," which harshly criticizes President George W. Bush. Encore, Mathers' fourth major-label album, was released later that year, but was considered by many to be a disappointment in comparison to his previous three albums and sold half of what The Eminem Show had. Though Eminem considers himself neither a militant nor a political artist, he did have his own Hip Hop Political Convention as a parody of the national political conventions held in 2004. His latest release is Curtain Call: The Hits, a compilation which covers many of his past hit songs, and includes three new tracks.

Eminem subsequently made high profile appearances on Rawkus Records' Soundbombing Volume 2 compilation and Missy "Misdemeanor" Elliott's Da Real World. He was also in the news when his mother filed a lawsuit claiming that comments made by the rapper during interviews and on The Slim Shady LP had caused, amongst other things, emotional distress, damage to her reputation and loss of self-esteem. None of which harmed the sales of Eminem's follow-up album, The Marshall Mathers LP, which debuted at number 1 on the US album chart in May 2000 and established him as the most successful rapper since the mid-90s heyday of 2Pac and Snoop Doggy Dogg. By the end of the year, however, his troubled personal life and a serious assault charge had removed the gloss from his phenomenal commercial success. Despite criticism from gay rights groups, the rapper swept up three Grammy Awards the following February. He also reunited with his D12 colleagues to record the transatlantic chart-topping Devil's Night.
