The solo project of Cris Oliveira, Nestor Durruti channels classic heavy and power metal through an explicitly anarchist lens, naming the band after the Spanish anarchist icon Buenaventura Durruti. The 2020 debut Passos includes a cover of Judas Priest's 'Electric Eye' alongside original material steeped in libertarian politics and melodic metal craft.

Newsonic channel the progressive grandeur of Dream Theater and Symphony X through a distinctly Brazilian lens, crafting dense, emotionally driven metal that occasionally drifts into symphonic territory. Their 2019 debut Vorax is an 11-track album tackling subjects ranging from social media dependency and mental health to mythology and natural disasters, anchored by powerful melodic vocals and a tightly constructed band sound. The group has been active since 2011 and built their reputation as one of Rio's stronger underground progressive metal outfits.
