Co-produced by Danger Mouse, Demon Days (2005) is the double platinum-certified second studio offering from the world's most famous virtual hip-hop group. The brainchild of Blur's Damon Albarn and Tank Girl co-creator Jamie Hewlett, the animated cast of characters from its innovative 2001 predecessor return - 2D (vocals), Murdoc (bass), Noodle (guitar/keyboards) and Russel Hobbs (drums) - alongside guests like De La Soul, Ike Turner, Dennis Hopper, MF Doom, Shaun Ryder, Neneh Cherry, Bootie Brown and the London Community Gospel Choir. Home to the catchy and cinematic singles "Feel Good Inc.," "Dare" and "Dirty Harry," New York's Paper called the album a "work of conceptual art that's as fulfilling to listen to as it is enjoyable to look at...more melodic, free-flowing and sharper-edged than on its predecessor."
