Call of the Mastodon collects the influential Atlanta metal band's earliest recordings. Remixed and remastered by longtime engineer Matt Washburn, five of the nine cuts, "Shadows That Move," "Welcoming War," "We Built This Come Death," "Hail to Fire," and "Battle at Sea," appeared on the group's 2001 debut EP, Lifesblood. The other four sound like they were from the same sessions, and rely heavily on the group's trademark bone-crushing rhythmic assault. Even in their formative stage, Mastodon - few groups manage to do such justice to their moniker - sound like seasoned vets, and while there may be nothing as seamless as 2004's "Blood & Thunder" or "Megalodon," Call of the Mastodon is a brutal blueprint for the group's signature Metallica-meets-grindcore mayhem.

Appearing near the dawn of the 21st century, Atlanta's Mastodon established themselves as one of the most original and influential American metal bands. Their wide-angle progressive approach encompasses stoner and sludge metal, punishing hardcore and metalcore, neo-psych, death metal, and more - sometimes in the span of a single song. The group's playing style incorporates heavy, technically complex guitar riffs, lyric hooks, long, melodic instrumental passages, and intricate, jazz-influenced drumming with syncopated time signatures. Their second album, 2004's Leviathan, was a concept offering based on Moby Dick, Herman Melville's iconic novel of whaling and obsession, and proved the band's commercial and critical breakthrough. Since its release, the record has attained status as one of the most important albums in heavy metal's history…

Pantera (/pænˈtɛrə/) was an American heavy metal band from Arlington, Texas, formed in 1981. The group's best-known lineup consisted of the Abbott brothers (drummer Vinnie Paul and guitarist Dimebag Darrell), along with vocalist Phil Anselmo and bassist Rex Brown…

In 2018, European progressive extreme music outfit the Ocean Collective released Phanerozoic I: Palaeozoic, the first half of a sprawling concept offering based on paleontology. Its companion, Phanerozoic II: Mesozoic | Cenozoic, closes the evolutionary cycle that spans all periods during the Phanerozoic Eon. The first album documented the Cambrian explosion that ended with the pre-Triassic extinction event. This chronological sequel begins at the dawn of the dinosaurs, then continues in the present epoch. Phanerozoic I: Palaeozoic garnered acclaim for its relentless heaviness and straightforward musical progression. Phanerozoic II is far more experimental and eclectic. Its sounds, words, and atmospheres are pursued in ever-expanding circles, employing varied tempos, abundant electronic textures, melodic compositional frames, and selective orchestration to create something that borders on the exotic, yet remains heavy as hell.
