A solo funeral doom project by André Barroso, best known as the founder and former guitarist and synthesizer player of the northeastern death-doom outfit Lacryma Sanguine. Man of Sorrows carries forward a similarly desolate atmospheric sensibility, trading Lacryma Sanguine's death-inflected approach for the glacial tempos and smothering weight of funeral doom.

Featuring vocalist Cris Maffra alongside guitarists Felipe Knoller and Ricardo Siqueira, Mandibulla occupied a corner of the stoner-doom spectrum enriched by classical strings and piano, setting their approach apart from the rawer side of the genre.
