A ritualistic project fusing black metal ferocity with the suffocating weight of doom, Malaise Shire conjures dense atmospheres rooted in darkness and despair. Their 2022 release "Painful Ritual of Despair" showcases a brooding blend of tortured riffs and ceremonial dread, recorded entirely in Paraíba.

Malakay was a black metal band from the interior of Minas Gerais whose approach leaned toward raw, uncompromising aggression. The band left behind recordings including the demo "Radicalism or Die" and the cassette album "The Edge Garden" before splitting up.

Malaria is a thrash metal and crossover band from Merlo, Buenos Aires, operating in the tradition of aggressive street-level metal with lyrical themes spanning war, social commentary, and the mosh pit. The band has self-released multiple recordings on Bandcamp, including a three-track demo (2016), the eight-track "Future Decimation EP" (2017), and the two-track "Piss Tape" (2018).

A nascent black metal project out of Rio de Janeiro, Malatanya emerged in 2024 with an outlook rooted in orthodox darkness and ominous atmosphere. Still in their early stages, the band channels the malevolent energy of the city's underground extreme metal scene.

Maldição is a metal-punk outfit steeped in the traditions of Motörhead, Venom, and Hellhammer, wielding abrasive riffs alongside pointedly anti-fascist, anti-capitalist lyrics. Releases like "Metal Punk Antinazi Demo" and "A Voz do Mal" cement their position at the crossroads of black metal rawness and punk confrontation.

Rooted in the fertile death metal underground of Porto Alegre, Malediction formed in the early 1990s when that city's scene was producing some of the continent's most intense extreme metal. Their output reflects the old-school brutality and direct aggression that defined Brazilian death metal in that era before the band eventually dissolved.

A long-running death-black metal force from the São Paulo underground, Malediction 666 draws heavily from the Greek black metal tradition — the 2019 album "We, Demons" even features guest appearances from Necroabyssious of Varathron and Sakis Tolis of Rotting Christ. The project is largely driven by a single individual, resulting in a focused and consistent sound shaped by decades of devotion to the dark arts.

Maleficarum brings a psychedelic sensibility to black metal from the scorched northeast of the country, threading hallucinatory textures through an otherwise bleak and hostile framework. Their 2021 release "Blocksberg Selecta" serves as an entry point into their occult-influenced sound, which sits at the intersection of ceremonial atmosphere and raw black metal abrasion.

Maleficio was a heavy/thrash metal band from San Fernando del Valle de Catamarca, Argentina, with a self-titled demo tape among their documented releases and a confirmed album entry "Go to Hell" listed on the Metal Archives. The band centred their lyrical themes on social denouncement and has since split up.
