Mastodon's fall tour with Dinosaur Jr. and Netherlands has been canceled due to the "critical situation" of a member of the Mastodon family. Tickets for the 13-date trek are available for refunds at point of purchase. While the band themselves have yet to comment on the cancelation, you can read tweets from two venues that were scheduled to host dates of the tour below.

Mastodon released their last studio album, Emperor of Sand, in 2017. It sold 41,000 traditional first-week units and notched them a Grammy win, which was Best Metal Performance for "Sultan's Curse." Drummer Brann Dailor recently revealed that they are planning on beginning to the writing process for their next record early next year.

"Once we get home, and we decompress from the Emperor Of Sand tour cycle, sometime early next year, we'll start dumping out the riffs and seeing what's new and seeing what's fresh and what we're digging on, and then we'll just start working — do what we normally do," Dailor told Consequence of Sound.
