All Hope Is Gone without their trademark masks circulated after band members appeared unmasked during performances with various side-projects. However, Shawn Crahan dismissed these rumors in an interview on
The Sauce. Bassist Paul Gray elaborated that the band would return with a new image; "It'll still be Slipknot," he stated, "but we're gonna upgrade, step things up a little." Beginning April 1, 2008, Slipknot's website displayed ten
teasers to promote
All Hope Is Gone. The first nine displayed the band in their purgatory masks, however, the final teaser featured a darkened photograph of the band with their new masks. Slipknot premiered their new masks on July 1, 2008 on
Spinner.com; eight million people visited the website to view the masks on the first day. On June 15, 2008, a 30-second sample and cover art from the album's title track, "
All Hope Is Gone", were made available on
Amazon.com. The song began
airplay the same day and on June 20, 2008, Roadrunner Records offered the track as a free download on their website. "All Hope Is Gone" was later released as a
digital single. The second single from the album, "
Psychosocial", began airplay on June 26, 2008 and was released as a digital single on July 7, 2008. Following the album's launch, "
Dead Memories" was released as a digital single on December 1, 2008, along with an accompanying music video. The music video for "Sulfur", the album's fourth single, premiered on April 18, 2009, and the single was released on June 15, 2009. From August 17 through 19, 2008,
Kerrang! magazine held six listening events across the United Kingdom which included a preview of the documentary supplied with the album's special edition, and free merchandise. On April 17, 2009, Roadrunner Records announced that the album would be released on
vinyl on April 19, 2009, coinciding with
Record Store Day. The album's cover art and track listing were released on July 8, 2008. Slipknot began its
All Hope Is Gone World Tour the following day—the tour was their first since 2005. The band initially toured with the
Mayhem Festival across the United States, through August 16, 2008. Afterward, Slipknot was scheduled to appear at the
Reading and Leeds Festivals in England, the Two Days a Week Festival in Austria, and the Area4 Festival in Germany. However, the European tour dates were canceled due to Jordison breaking his ankle. Slipknot performed at the
Rock on the Range Festival on May 16 and 17, 2009 then headlined the
Download Festival in England during the summer, the first time they had headlined the festival. ==Music and lyrics==
