Voliminal: Inside the Nine is the third video album by American metal band Slipknot. Released December 5, 2006 by Roadrunner Records, the 2-disc DVD set features an 84-minute movie created by band member Shawn "Clown" Crahan. The set also includes live performances, music videos from songs on the band's third studio album, Vol. 3: (The Subliminal Verses), and the first unmasked interviews with all of the band members. The movie featured footage recorded from the recording of Vol. 3: (The Subliminal Verses) through the end of the tour in support of the album spanning a total of 28 months. The DVD was promoted on various websites for the weeks leading up to its limited theatrical release. Critical reception of the album was mixed, Dawn wrote the album has "a raw sound" calling it "an audible treat for thrash and speed metal fans". However, Billboard would tell fans to "save your cash for the band's next tour".Voliminal would be certified gold, platinum, and double platinum in Australia, the United States, and Canada respectively.

The initial idea for the DVD came to percussionist Shawn Crahan, three weeks before the band entered The Mansion in 2003, where they would work on their third studio album Vol. 3: (The Subliminal Verses). Crahan received help from the band's record label Roadrunner, who supplied them with tapes, camera cleaning equipment and funds to hire people to operate the cameras when Crahan himself couldn't. Recording began when Slipknot entered The Mansion and continued until they had finished touring in 2005, reportedly covering 28 months of the bands time together. Crahan's intentions were to capture as many different Slipknot situations as he could, so when the opportunity to produce a DVD came, he would be in a position to begin work immediately. During the period in which the footage was being shot, Crahan began making little tests of the footage and revealed them to his fellow band mates, judging their reactions to help him establish areas of interest from them. The whole recording process produced over 300 60-minute tapes of footage.
