Continuing their promotion of last year's The Desaturating Seven, Primus have announced a two-month tour of the U.S. They'll be joined on the road by Mastodon.

They'll begin on May 6 at Red Rocks in Morrison, Colo., and wrap it all up on July 7 at Phoenix's Comerica Theatre. Tickets for all shows go on sale to the general public this Friday with a pre-sale beginning tomorrow with the password "Goblins." You can see all the dates below and get full ticketing details at Primus' website.

The Desaturating Seven was based on a book called The Rainbow Goblins by Ul Del Rico that Primus frontman Les Claypool used to read to his children. The plot centers on seven goblins who "pull the color out of the world."

"The dark imagery and beauty of the art struck me immediately, and I thought, 'This would make good fodder for a piece of music,'" he said. "The use of color and darkness both in the paintings and the writing was compelling and now, near two decades later, the metaphor of greed, gluttony and deceit vs. unity of the masses is eerily relevant. I brought the notion to the Primus guys and they were all for it. Plus, I figured it's about time someone brought 'Goblin Rock' back to the fold."

Last night, Mastodon took home the Best Metal Performance Grammy for "Sultan's Curse." The track, which the band cross-promoted with its own beer, appeared on Emperor of Sand.
