Inspired by "The Grey Album", which collaborative EP by Jay-Z and Linkin Park was released in 2004?
Collision Course (album) Collision Course is a collaborative EP from American rapper Jay-Z and nu metal band Linkin Park, released on November 30, 2004 by Roc-A-Fella, Machine Shop, Warner Bros. and Def Jam records. Before the album, Jay-Z had released collaborations with The Roots and R. Kelly, and Linkin Park had collaborated with various artists on their remix album Reanimation. The album was inspired by "The Grey Album" by Danger Mouse, which was a mash-up album between Jay-Z and The Beatles. MTV had originally planned on mashing up only one or two songs, but the project was eventually expanded to a six-song EP. The album was mostly produced by Mike Shinoda and Jay-Z, and was recorded between July 16 and July 19.
Relapse (Eminem album) 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.
