Later this month, the deathlessly wacky Bay Area funk-metal power trio will return with their new album The Desaturating Seven, a concept album based on a children’s book about a group of goblins who steal the color from the world. It’s the first Primus album of new songs in six years, and it’s the first to feature all three original members since 1995. We’ve already posted the deeply off-kilter first single “The Seven,” and now they’ve also shared “The Scheme,” a proggy rumble that’s built on a math-rock time signature. Give it a listen below.

The Desaturating Seven is out 9/29 on ATO.
