Boston's Mentalist occupy a peculiar and rewarding niche — black metal bent through experimental sensibilities that resist easy categorization, formed in 2019 in a city better known for hardcore and prog than for the corrosive. Their music uses black metal's core vocabulary of blast beats and tremolo-picked dissonance as a launching pad for stranger structural decisions, subverting the genre's orthodoxies from within. In a city with a strong tradition of intellectual extremity, Mentalist fit right in while standing apart from most of their contemporaries.

California's Meticulous Butchery push brutal death metal into genuinely experimental territory, a combination that their Metal-Archives tag — Experimental Brutal Death Metal — only begins to describe.

Their name is both descriptive and a kind of mission statement: precision applied to carnage.

Moon Twin is a Corona, California experimental death metal project formed in 2017, pushing the genre's boundaries through unconventional song structures and a willingness to absorb influences from outside metal entirely.
