Graduation is the third studio album by American hip hop artist Kanye West, released September 11, 2007 on Roc-A-Fella Records. Recording sessions for the album took place during 2005 to 2007 at Chung King Studios and Sony Music Studios in New York City and at Chalice Studios and The Record Plant in Los Angeles. It was primarily produced by West and DJ Toomp, and features guest contributions from artists including Mos Def, Dwele, T-Pain, Lil Wayne, and Chris Martin of Coldplay. The album's cover artwork was designed by Japanese artist Takashi Murakami. Inspired by Irish rock band U2 and other musical groups to make more inspirational, anthemic hip hop music, West incorporated synthesizer sounds into his production and dabbled with electronic music, while sampling a wider spectrum of musical genres. Lyrically, Graduation is more introspective in comparison to its predecessors, as West dedicated much of the album towards analyzing himself and conveying his ambivalent outlook on his newfound fame. It continues the education theme of West's previous two studio albums, The College Dropout (2004) and Late Registration (2005). The album debuted at number one on the US Billboard 200 chart,…
