Context: The Marshall Mathers LP 2 is the eighth studio album by American rapper Eminem.  Aftermath Entertainment, Shady Records, and Interscope Records released the album on November 5, 2013.  It serves as a sequel to "The Marshall Mathers LP" (2000).  The album's production and its recording sessions were conducted from 2012 to 2013, involving Eminem himself, along with several record producers including Rick Rubin, Luis Resto, Emile Haynie, and Alex da Kid.  "The Marshall Mathers LP 2" features guest appearances from singers Skylar Grey, Rihanna, Nate Ruess, and rapper Kendrick Lamar. The Marshall Mathers LP is the third studio album by American rapper Eminem.  It was released on May 23, 2000, by Aftermath Entertainment, Interscope Records, and Eminem's newly founded label, Shady Records in the United States, and on September 11, 2000, by Polydor Records in the United Kingdom.  The album was produced mostly by Dr. Dre and Eminem, along with The 45 King, the Bass Brothers, and Mel-Man.  Released a year after Eminem's breakout album "The Slim Shady LP", the record features more introspective lyricism including the rapper's response to his sudden rise to fame and controversy surrounding his lyrics. American rapper Eminem's music has been released on record labels Web Entertainment and Interscope Records, along with subsidiaries Aftermath Entertainment, Goliath Artists and his own Shady Records.  Eminem is the best-selling hip-hop artist of all-time and the best-selling artist of the 2000s with US album sales at over 32.2 million during the decade.  As of November 2010, Eminem has four songs that have sold over three million downloads in the United States.  Eminem has sold more than 42 million track downloads in the United States alone.  His worldwide albums and singles sales stand at more than 172 million.  He has earned forty-two platinum certifications, five number one singles and six number one albums from the Recording Industry Association of America (RIAA).  In this discography, music videos and collaborations are included as well. Relapse is the sixth studio album by American rapper Eminem.  The album was released on May 19, 2009, under Aftermath Entertainment, Shady Records, and Interscope Records.  It was his first album of original material since "Encore" (2004), following a four-year hiatus from recording due to his writer's block and an addiction to prescription sleeping medication.  Recording sessions for the album took place during 2007 to 2009 at several recording studios, and Dr. Dre, Mark Batson, and Eminem handled production.  Conceptually, "Relapse" concerns the ending of his drug rehabilitation, rapping after a non-fictional relapse, and the return of his Slim Shady alter-ego. "Mockingbird" is a song by American rapper Eminem from his fifth studio album "Encore" (2004).  It was released as the fifth single from the album in April 2005.  It peaked at number eleven on the "Billboard" Hot 100, and number four in the United Kingdom.  It received a Grammy nomination for Best Rap Solo Performance.  "Mockingbird" was later included on Eminem's greatest hits compilation album "" (2005). The Eminem Show is the fourth studio album by American rapper Eminem, released on May 26, 2002 by Aftermath Entertainment, Shady Records, and Interscope Records.  "The Eminem Show" includes the commercially successful singles "Without Me", "Cleanin' Out My Closet", "Superman", and "Sing for the Moment". Slim Shady EP is the 1997 debut extended play by American rapper Eminem, through the Detroit-based record label Web Entertainment.  Unlike "Infinite", "Slim Shady EP" helped Eminem gain the interest of CEO Jimmy Iovine (co-founder of Interscope Records) and West Coast hip-hop producer Dr. Dre, who subsequently signed Eminem to his Aftermath Entertainment record label, and served as executive producer on his major-label debut album "The Slim Shady LP" (1999).  Dre also served as executive producer on Eminem's later albums such as "The Marshall Mathers LP" (2000), "The Eminem Show" (2002), "Encore" (2004), "" (2005), "Relapse"-"Refill" (2009), "Recovery" (2010), and "The Marshall Mathers LP 2" (2013). Recovery is the seventh studio album by American rapper Eminem.  It was released on June 18, 2010, by Aftermath Entertainment, Shady Records, and Interscope Records as the follow-up to Eminem's "Relapse" (2009).  Originally planned to be released as "Relapse 2", the album was renamed to "Recovery" when Eminem found the music of the new album different from its predecessor. Encore (stylized as ƎNCORE) is the fifth studio album by American rapper Eminem.  It was released by Aftermath Entertainment, Shady Records, and Interscope Records.  Its release was set for November 16, 2004, but was moved up to November 12 (coincidentally, exactly eight years to the day since his debut album, "Infinite", was released) after the album was leaked to the Internet.  "Encore" sold 710,000 copies in its first three days, and went on to sell over 1.5 million copies in its first two weeks of release in the United States, certified quadruple-platinum that mid-December.  Nine months after its release, worldwide sales of the album stood at 11 million copies.  By December 2016, the album had sold over 5 million copies in the United States and more than 23 million copies worldwide. The Slim Shady LP is the second studio album and the major-label debut by American rapper Eminem.  It was released on February 23, 1999, under Interscope Records and Dr. Dre's Aftermath Entertainment.  Recorded in Ferndale, Michigan, in the US, following Eminem's recruitment by Dr. Dre and Jimmy Iovine, the album features production from Dr. Dre, the Bass Brothers, and Eminem himself.  The majority of the album's lyrical content is written from the perspective of the rapper's alter ego Slim Shady, whom the rapper created on the "Slim Shady EP" (1997).  The lyrics are noted for their over-the-top depictions of violence and heavy use of profanity.
