SLIPKNOT frontman Corey Taylor is back in the studio laying down vocal tracks for the band's long-awaited new album.
On Tuesday, Taylor posted an Instagram photo of him in what appears to be a recording booth along with the caption: "Back to work…"
SLIPKNOT's sixth album is tentatively due this summer.
The new disc is once again being recorded at a Los Angeles studio with producer Greg Fidelman, who engineered and mixed SLIPKNOT's 2004 album "Vol. 3: (The Subliminal Verses)" and helmed ".5: The Gray Chapter".
Corey recently described the band's new music as "evil," adding that the follow-up to 2014's ".5: The Gray Chapter" is "going to be ridiculous. Let's put it that way."
According to Taylor, SLIPKNOT's recently released standalone single "All Out Life", which arrived last October isn't "nearly as dark and vicious as the rest of the stuff that we have that we're working on."
Taylor said he wrote "All Out Life" in part because he didn't see others using music as a force to "take a hard look at what you believe."
He explained: "People are way too pissed about the wrong things and not pissed enough about the right things. "[The song sets] the tone for getting people to stand up and go, 'We're not gonna allow this. We're not gonna allow people to run us down for religious beliefs, for the color we are, for what we stand for. For who we chose to love.' All of these things. There's nobody doing it, man. Everybody's too worried about their pockets. Everybody's too worried about their paychecks.
"That was me, basically, drawing a line in the sand and going, 'Guess what? You don't get to do this anymore,'" he added.
Some of SLIPKNOT's new album will also deal with Taylor's depression that led to a divorce and forced him to "figure out who I was" without relapsing into substance abuse.
"All I was doing was giving and I found myself absolutely, completely tapped," he said. "You could see it in my skin. You could see it in my eyes. That's basically the journey I'm going to take people on this album … show them what happens to depression when you have no chemicals to fall back on.
"It's a pretty dark ride."
SLIPKNOT's video for "All Out Life" was directed by the band's own M. Shawn Crahan.
".5: The Gray Chapter" was released following a six-year hiatus during which founding SLIPKNOT bassist Paul Gray died and drummer Joey Jordison was dismissed.
".5: The Gray Chapter" sold around 132,000 copies in the United States in its first week of release to land at position No. 1 on The Billboard 200 chart. The CD arrived in stores in October 2014 via Roadrunner.
Gray died in 2010 from a drug overdose, while Jordison was let go in December 2013, just before SLIPKNOT began recording the last album.
