The metalheads of Lamb of God and Mastodon are heading out on a co-headlining tour across North America to celebrate the 20th anniversary of their 2004 hit albums.

Lamb of God will be honoring Ashes of the Wake, while Mastodon will celebrate Leviathan. Both records were released on August 31, 2004, cementing their spot in the metal community. Fans will see the group play both albums in-full, performing hits like Lamb of God’s “Laid to Rest” and “Ometa,” as well as Mastodon’s “Blood and Thunder” and “Iron Tusk.”

The “Ashes of Leviathan Tour” is set to kick-off on July 19 at the Texas Trust CU Theatre in Grand Prairie. From there, they’ll appear in Raleigh, Bangor, Calgary, Portland, and El Paso, making stops along the way at venues like Jacobs Pavilion in Cleveland, Mohegan Sun Arena in Uncasville, Quebec’s Bell Centre, and the legendary Red Rocks Amphitheatre in Morrison. They’ll wrap things up on August 31 — celebrating the official 20-year anniversary of both records — at The Astro Amphitheatre in Omaha.
