Negativus blends old-school death metal with groove-laden heaviness, drawing on the sounds of Obituary, Entombed, and Celtic Frost while writing all their lyrics in Portuguese.

Nekkrofuneral deals in old-school black/death savagery rooted in the Brazilian underground tradition, with Z. Misanthrope on bass and vocals, M. Marra on guitars, and C. Couto on drums.
