Mastodon has revealed that Valient Himself will be making a guest appearance on the band's upcoming album. Guitarist Brent Hinds posted a picture of him with the Valient Thorr singer on Instagram on January 16th along with the caption "@valient_himself doin some sweet gang vox with my boy."
Valient Thorr supported Mastodon on the band's 2010 US headline tour. Their sixth album, "Our Own Masters," was released in June 2013 to high critical acclaim. The record was produced by Kyle Spencer.
Speaking with Metal Hammer last week, Mastodon guitarist Bill Kelliher noted that the band is looking to surprise fans with the new album:
"I've spent a lot of time writing over the last six months, trying to come up with new ideas. Every Mastodon record seems to have a different flavor - we don't want to keep on releasing the same record over and over again. We've got to surprise our fans; we're always moving and growing."
