Fret not, Mastodon fans who've missed the rockers on their tour behind last year's Once More 'Round the Sun: The band is heading out on tour yet again through the end of this year. Heavy metal stalwarts Judas Priest will join for a good chunk of the dates, while others will include Clutch and Corrosion of Conformity.

On Tuesday the four-piece revealed a string of dates beginning in September and stretching all the way to December. A North American tour runs October through November, with the outliers on either side being international festival dates.

The tour announcement comes nearly a month and a half after Mastodon dropped their "Asleep in the Deep" video, which is still as ridiculous as it was in June. Have you even recovered from the last time you watched this cat's journey into mind-bending puppet-fueled madness? Absolutely not, but you should watch again anyway. 

Mastodon are currently at work on their seventh new album. A release date is unknown, but it's not out of the question to imagine new material might get tested on this tour with Priest.
