808s & Heartbreak is the fourth studio album by the American rapper Kanye West. It was released through Def Jam Recordings and Roc-A-Fella Records on November 24, 2008. West recorded it between September and October 2008 at Glenwood Studios in Burbank, California and Avex Recording Studio in Honolulu, Hawaii, and produced it with assistance from No I.D., Plain Pat, Jeff Bhasker, and Mr Hudson. Guest appearances include Kid Cudi, Young Jeezy, Mr Hudson, and Lil Wayne. West conceived 808s & Heartbreak following the death of his mother Donda in November 2007 and his breakup with his then-fiancée Alexis Phifer in April 2008. It marked a major artistic departure from his previous hip-hop records; West mostly sings instead of rapping, with vocals processed through Auto-Tune against an electronic production and minimalist sonic palette, including prominent use of minor keys and the Roland TR-808 drum machine. Lyrical themes include loss, heartache, and West's struggles with pop stardom.
