Over the past several weeks, Slipknot have been unveiling songs off their new album '.5: The Gray Chapter.' Well, now fans can stream the entire disc ahead of its release on Tuesday, Oct. 21.

Head over to www.5thegraychapter.com to listen to the whole album. Upon visiting the site, the leadoff cut 'XIX' automatically plays followed by the rest of the tracks on the disc.

Fans got their first taste of '.5: The Gray Chapter' with the song 'The Negative One.' That track was shortly followed by the release of the disc's official first single, 'The Devil in I,' for which the band also unleashed a creepy music video.

Slipknot will be headlining their very own Knotfest on Oct. 25 and 26 in San Bernardino, Calif. The band will then embark on the Prepare for Hell tour with support from Korn. See Slipknot's full list of dates here, and pick up '.5: The Gray Chapter' at iTunes.
