All Hope Is Gone is the fourth studio album by American metal band Slipknot. Released on August 20, 2008 by Roadrunner Records, the album was published in two versions: the standard album in a CD case and a special edition packaged in a six-fold digipak containing three bonus tracks, a 40 page booklet, and a bonus DVD with a documentary of the album's recording. Preparation for the album began in 2007, while recording started in February 2008 in the band's home state of Iowa. Before the album's launch, Slipknot released a series of promotional images and audio samples from the album through various websites. All Hope Is Gone is considered the band's most eclectic-sounding album, incorporating elements from their previous three. Songs such as the opening track "Gematria" and the title track espouse the band's more brutal, death metal-influenced edge, reminiscent of songs such as "" from their debut self-titled album; slow burning, "trippy" elements such as "Gehenna", reminiscent of "Skin Ticket" from their second album Iowa; and more tragic, sentimental tracks such as "Dead Memories" and "Snuff".
