Diamond Hoo Ha is the sixth and final studio album by British alternative rock band Supergrass, released in the UK on 24 March 2008, and offers a return to punchier Supergrass songs, in comparison to the more mellow Road to Rouen, their previous album released in 2005. Several songs appearing on the album were performed at Guilfest 2007. In November 2007, the track "Diamond Hoo Ha Man"—one of the songs debuted at Guilfest—was distributed as the first single on a limited vinyl release, restricted to 1500 copies. "Bad Blood" followed as the second single on 17 March 2008, peaking in the top 75 at number 73.
