Demon Days is the second studio album by British virtual band Gorillaz, released in May 2005. The album features contributions from De La Soul, Neneh Cherry, Martina Topley-Bird, Roots Manuva, MF DOOM, Ike Turner, Bootie Brown of the Pharcyde, Shaun Ryder, Dennis Hopper, the London Community Gospel Choir, and the Children's Choir of San Fernandez. Albarn brought in Danger Mouse as producer.

Demon Days entered the UK charts at #1 and the U.S. charts at #6, outperforming the band's 2001 debut, Gorillaz. The album has sold eight million copies worldwide. The album features the singles "Feel Good Inc.", "DARE", "Dirty Harry" and "Kids with Guns"/"El Mañana". Much like 2001's Gorillaz, the release of Demon Days and its respective tour were accompanied by various multimedia. These included interactive features on the Gorillaz website, a total of four animated music videos, virtual interview sessions with the band and animatics for each song. Almost all of the visuals associated with the album were designed by Gorillaz co-creator Jamie Hewlett as his design company, Zombie Flesh Eaters. Spin ranked Demon Days as the fourth-best album of 2005, while Mojo ranked it at number eighteen on their year-end list and hailed the album as a "genre-busting, contemporary pop milestone." NME placed it 98th on their list of 100 greatest albums of the decade.Uncut ranked it at 75 on their list of top 150 albums of the decade.Complex included it on their list of 100 Best Albums of the Complex Decade, placing it at number 43.Spin later included it in their list of The 300 Best Albums of 1985–2014.
