Neuro Attack plays straight-ahead thrash metal rooted in the classic Minas Gerais underground, formed in 2016 and quickly releasing their debut EP Thrash Returns before following it with a full-length in 2018.

Neurotóxico brought a technically ambitious edge to the Brasília extreme metal scene, blending aggressive thrash foundations with death metal dissonance on their 2015 debut demo Web of Terror.

The project of guitarist and vocalist Tiago Torres, a veteran of the Brazilian scene through his work with Mad Dragzter, No More Death channels the fury of Metallica, Slayer, and early Sepultura into a decidedly spiritual framework, with lyrics drawn from the Book of Revelation.

NoWrong deliver punishing thrash metal with a blunt fixation on politics, social inequality, and modern urban violence, channeling those themes across the 13 tracks of their 2014 debut Prognostic of a Great Disaster.
