Ferocious Speed / Thrash Metal from Houston.

Kent, Ohio's Master Bastard play hard-driving thrash metal with a blue-collar aggression that's entirely at home in a post-industrial college town. Formed in 2023, they waste no time establishing what they're about.

Portland's Master Burial conjures suffocating walls of raw, atmospheric black metal soaked in despair and Pacific Northwest bleakness. Formed in 2021, the project channels depressive DSBM traditions through a lo-fi haze that feels genuinely harrowing.

Since 1990, New Jersey's Mastermind has been a fixture in American progressive metal, weaving complex song structures and virtuosic musicianship into long-form compositions. Their decades-long run out of Browns Mills stands as a testament to the resilience of prog metal outside major scenes.

Atlanta's Mastodon have charted one of metal's most ambitious creative arcs, evolving from the relentless sludge metal fury of 'Remission' through the progressive concept albums 'Leviathan' and 'Crack the Skye' into the melodic grandeur of 'Emperor of Sand.' Their four members each contribute vocals, lending a layered harmonic complexity rare in heavy music, while Brent Hinds and Bill Kelliher's intertwining guitar work stands among the most distinctive in modern metal. Grammy-winning and platinum-selling, Mastodon have proven that uncompromising artistic evolution and commercial success can coexist.

Columbia City, Indiana's Matanza evolved from metalcore roots into a brutalizing blend of death metal and grindcore — all velocity, grit, and aggression with zero compromise. Their trajectory mirrors a band shedding its skin in pursuit of something far more savage.

Mathrem is a Death Metal band from Ambato, Tungurahua, Ecuador. Their 2019 release "Profecias y Ruinas" established them as an independent act working within the Ecuadorian underground extreme metal scene. The band operates without label support, self-releasing their material on Bandcamp.

Named after Southeast Asian folklore's restless spirits, Chicago's Matianak channels that dread into cold, menacing black metal. Their work since 2016 carries the dense urban edge of the Midwest filtered through an icy, unrelenting aesthetic.

Saint Paul's Matrekis delivers straightforward heavy metal with a blue-collar Minnesota sensibility — nothing flashy, just riffs built to last. Active since 2013, they keep the traditional metal flame burning in the Twin Cities underground.
