Primus and Mastodon will unite this summer for a massive U.S. tour. The co-headlining, 43-date trek launches May 6th in Morrison, Colorado and concludes July 7th in Phoenix.

The joint trek promotes the bands' respective 2017 projects. Last year, Mastodon released their seventh LP, Emperor of Sand, and a follow-up EP, Cold Dark Place, featuring a new song, "Toe to Toes," and three leftover tracks from the sessions of 2014's Once More 'Round the Sun.

Primus issued their ninth album, The Desaturating Seven, a concept record themed around the Italian author Ul de Rico's 1978 children's book, The Rainbow Goblins. That LP marked the first album of original material from the acclaimed line-up featuring bassist-singer Les Claypool, guitarist Larry "Ler" LaLonde and drummer Tim "Herb" Alexander.

In February, Mastodon bassist Troy Sanders, Pearl Jam's Jeff Ament, the Kills' Alison Mosshart, No Doubt's Tony Kanal, Queens of the Stone Age's Troy Van Leeuwen and other musicians will auction off their artwork in support of a Los Angeles children's learning center. Sanders' band Gone Is Gone is scheduled to perform at the event.
