Brazilian extreme progressive metal band active since 2018, combining the technical complexity of progressive metal with the aggression of extreme subgenres. Operating largely under the radar of major metal press, they maintain their output on Bandcamp as part of the growing underground progressive extreme metal scene in Brazil.

Enigma Ex Machina is an extreme progressive metal band from São Paulo, Brazil, formed in 2020 by André Vaz and Renato "Timbó" Machado, later expanded with drummer Artur Guedes and bassist João Castañon. The band explores lyrical themes of mental health and astronomy, and released their EP "The Event Horizon" in December 2020.

Mulmeyun is a Santiago-based extreme metal project blending symphonic, black, and gothic doom elements, with the project's first release, the two-track EP A Tale of Love, appearing in September 2018. The band uses a Vocaloid voice bank as vocalist, an unusual choice within the Chilean metal underground, and has released a steady stream of material including Struggle (2020) and An Ancient Calling (2021). Thematically, the project frames suffering and sacrifice as necessary responses to modern nihilism and existential despair.
