A one-man death metal project from Espírito Santo, Brazil, built around uncompromisingly anti-religious lyrical themes. The project has released at least two albums — "O Inferno te Espera" and "Crucificado pela Ignorância" — channeling the blunt, aggressive tradition of Brazilian extreme metal with a blasphemous conceptual focus. It operates as a fully independent solo endeavor, distributing its material through Bandcamp.

A short-lived Brazilian solo project by Lucylove, blending black metal, death metal, grindcore, and noise into what the artist described as "Brazilian deathgrind crust." Their 2022 debut EP "Anti-Fa, Anti-You, Anti-All," released through No Profit, No Money Records, packs ten tracks of nihilistic extremity, with chaotic noise textures and lyrical themes centered on emptiness and anti-authoritarian rage. A second EP, "The Nekrocrust," followed in October 2023 before the project disbanded.

A black metal project from Rio Grande do Sul, Brazil, active briefly from 2018 before disbanding. The state has a deep tradition of underground extreme metal — home to Krisiun, Brutal Morticínio, and numerous other acts — and Antigo represents a later generation of that regional underground. Details on the project's lineup and releases are sparse, reflecting the deeply DIY and underground nature of the Brazilian black metal scene in the southernmost state.

Antiklan is a post-doom and sludge metal trio from Natal, Rio Grande do Norte, Brazil, formed in 2022. The band — vocalist Julia Gusso, guitarist and bassist Flávio França, and drummer Max Barros — released their debut album 'Under Wetiko (Hymns from beneath the Veil)' in 2022, a five-track record recorded at Studio Black Hole in Natal and mixed in São Paulo. Their heavy, socially charged sound blends sludge and doom with an explicitly DIY, anti-authoritarian ethos, earning comparisons to punk-infused sludge.

Antikristo is a Black/Speed Metal band from Popayán, Colombia, formed in 2008. The band released several demos and splits before issuing their debut full-length Oscuro portador de luz, dador de visión eterna in 2019, followed by the EP Caos Ecsai in 2020 via Hellhoundz Productions.

Antimonument is an anonymous Brazilian extreme metal collective that emerged in 2021, fusing black metal, death metal, grindcore, hardcore punk, industrial noise, and power electronics into what they describe as a degenerative audio-visual ritual. Their debut album 'Concealment' appeared on CD via Cianeto Discos and cassette via Red Door Records before Sentient Ruin Laboratories issued an expanded vinyl edition with bonus tracks and a new master by Will Killingsworth. Drawing comparisons to Blasphemy, Incantation, Khanate, and Godflesh, the project operates with a deliberately depersonalized, collective identity.

Antireligion is a São Paulo-based one-man black/thrash metal project formed in 2011, rooted firmly in the old-school tradition of the genre. The project has released demos including 'Total Desolation' and 'Demo II: Unholy Blasphemies 2012–2014', channeling the raw, aggressive spirit of early Brazilian and European black/thrash pioneers. Lyrically, the project centers on anti-religious themes consistent with the second-wave black metal tradition.

Antro were a heavy and stoner metal band from Teresópolis, Rio de Janeiro, Brazil, active from 2014 until their split-up. Rooted in the fuzzed-out, riff-driven tradition of stoner and heavy metal, the band was part of a small but vibrant underground scene in the mountainous Serrana region of Rio de Janeiro state. They operated independently and released music through Bandcamp.

Antroforce is a thrash metal band from Carapicuíba, in the western zone of greater São Paulo, Brazil, formed as a tribute to the 1980s Brazilian metal underground — citing Dorsal Atlântica, Mutilator, Vulcano, and early Sepultura as primary influences. The band sings in Portuguese and released their self-titled debut full-length in 2019 on Bigorna Records, following a split with Harpago in 2015 and two earlier demos. Their 2021 single 'Sinfonia do Diabo' and subsequent album 'Antropocaos' show a band evolving within the classic Brazilian thrash framework.
