MASTODON will support the Hirshberg Foundation For Pancreatic Cancer Research. After their manager Nick John tragically passed away from pancreatic cancer in 2018, MASTODON partnered with the organization and has raised nearly $60,000 to fight the disease and support researchers and patients around the globe. The Hirshberg Foundation For Pancreatic Cancer Research is focused on finding a cure for pancreatic cancer, and empowering patients and families whose lives are touched by this disease. Founded in 1997, the Hirshberg Foundation funds groundbreaking scientific research, provides patient education and support, and sustains hope that this cancer will be eradicated once and for all.

"Leviathan", released on Relapse Records, was MASTODON's first concept album, loosely based on the 1851 novel "Moby-Dick" by Herman Melville. Three magazines named the LP "Album Of The Year" in 2004: Revolver, Kerrang! and Terrorizer. In 2009 and 2015, MetalSucks named "Leviathan" the best metal album of the 21st century. "Leviathan" was also released with an audio DVD in a limited-edition set with a black-and-gold slipcase.

MASTODON's latest studio album, "Hushed And Grim", a double LP recorded at the band's Atlanta studio, West End Sound, was produced by David Bottrill (TOOL, RUSH, MUSE, PETER GABRIEL). This album, their most expansive song-cycle to date, features 15 distinct tracks and achieved their third consecutive No. 1 debut on the Billboard Hard Rock Albums chart. "Hushed And Grim" also earned them a Grammy Award nomination for the track "Pushing The Tides". Additionally, the album's single "Teardrinker" secured a top 10 position on the rock radio charts, a further testament to the band's widespread acclaim.
