All Hope Is Gone is the fourth studio album by American alternative metal band Slipknot. Released on August 20, 2008 by Roadrunner Records, the album was published in two versions: the standard album in a jewel CD case and a special edition packaged in a six-fold digipak that contains three bonus tracks, a 40-page deluxe booklet, and a bonus DVD containing a documentary of the album's conception. The album was Slipknot's first to reach the number one spot on the Billboard 200, doing so in its debut week.
Preparation of the album began in 2007, and in February 2008 the band began working in the studio. It is the band's first studio album since 2004's Vol. 3: (The Subliminal Verses), and it is their fourth studio album as well as the first musical output from the band since Corey Taylor and Jim Root's mainstream success with Stone Sour; Joey Jordison's stints with Korn, Ministry, and 3 Inches of Blood; Shawn Crahan's side project Dirty Little Rabbits; and Sid Wilson's solo project. All Hope Is Gone is also the band's first studio album released by a major label to be recorded in their home state of Iowa.
