Morbid Holocaust is a black metal band from Valparaíso, Chile, operating primarily as a one-man project under the name Holocausto. The band released their debut album Atmospheric Armageddon in 2017, recorded at Calaka Records in Valparaíso, and the full-length Conexiones in 2023, the latter tracked between 2021 and 2023 at IIgniter Studios in Limache; they also contributed to the five-band split En el Caos de la Oscuridad alongside Morgue, Kalkü, Beelzebuth, and Ausencia in 2023.

Morbidoom trace their roots back to 1993, making them one of the older black metal outfits from the interior of Minas Gerais. The band documented their early phase through the demo tapes Seven Swords of Lucifer (1995) and Ares... The Call of War (1999), drawing on warrior mythology and occult themes before going dormant and eventually returning to activity around 2015.

Mordrean is a one-woman black metal project by Demona, rooted in raw, winter-drenched atmospheres drawn from anti-Christian philosophy and dark paganism. The debut demo "Under the Black Frost" arrived in 2014, and the project has continued to grow, culminating in the 2023 full-length "In Memoriam Tenebris" released through Dominance of Darkness Records.

Morgue is a black metal band from Quilpué in Chile's Quinta Región, active within the regional underground scene alongside bands such as Kalkü and Beelzebuth. The band contributed two tracks, "Olvidado Resplandor" and "Arcano XIII", to the 2023 five-band split En el Caos de la Oscuridad, recorded at CIRAR Metal Records in Peñablanca.

Morri fuses blackened thrash with the abrasive energy of crust punk, drawing on the raw aggression shared between those worlds. Their 2019 EP "Não Existe Vida," recorded at LF Studio in Realengo, announced a band with no interest in polish — just velocity, hostility, and grime.

Led by guitarist and vocalist Fabrício Moraes, a veteran of the Brasília metal scene through his work in Dark Avenger and several other local acts, Mortaes debuted in 2007 with the album "Obsessive Visions" on Die Hard Records. The band blends death and black metal with neoclassical guitar flourishes, and the debut featured guest contributions from members of Dr. Sin, Khallice, and Miasthenia.
