Mastodon and Clutch have announced that they are heading out on 'The Missing Link Tour,' a co-headlining spring trek. In addition, they’re bringing special guests Graveyard and Big Business along for the ride.

On most of the dates, Mastodon will close the show, but Clutch will be the final performers in several cities, including Pittsburgh, Baltimore and Columbus, Ohio. Tickets go on sale this Friday and you can buy them here or here.

Mastodon released their latest disc, ‘Once More ‘Round the Sun,’ in June 2014. Their sixth studio album became their highest chart debut ever, landing at No. 6 on the Billboard 200 tally. They also nabbed a Grammy nomination for 'Best Metal Performance' for 'High Road' off of the disc.

Clutch are currently working on their next album, a follow-up to 2013's critically acclaimed ‘Earth Rocker.'
