Mastodon have unveiled plans for a major North American headlining trek this fall. Dubbed “The Poisonous Weapons Tour,” the run will see the Atlanta metal veterans joined by special guests Deafheaven and Alcest for a series of dates across the United States and Canada.
The extensive tour kicks off on September 16 in Orlando, Florida, and will make stops in cities including Philadelphia, Brooklyn, Toronto, Chicago, Los Angeles, Denver and Atlanta before wrapping up on October 24 in Dallas, Texas.
The announcement arrives on the same day Mastodon released their new single, “Your Ghost Again.” The track marks the band’s first new music since the passing of founding guitarist and vocalist Brent Hinds in 2025 and serves as the latest glimpse into the group’s next chapter.
Song credits for “Your Ghost Again” also confirm playing and writing contributions from guitarist Nick Johnston and keyboardist João Nogueira, both of whom have become part of Mastodon‘s evolving lineup.
Fans looking to attend the upcoming tour can purchase tickets through the ongoing artist presale. General ticket sales are scheduled to begin on Friday, June 5, at 10 a.m. local time.
