Ashtoreth is a doom/black metal band from Florianópolis, Santa Catarina, whose music is steeped in the mythology and folklore of the city known as the "island of magic." Their 2022 debut album Bruxólico — released on Dejeto Sonoro Records — weaves distorted guitars, unconventional percussion including a zither, and varied vocal approaches into six tracks across 40 minutes, drawing on local witchcraft legends and the poetry of Symbolist writer João da Cruz e Sousa. The album is envisioned as the first part of a trilogy.

A one-man black metal project from Santa Fé do Sul in the extreme northwest of São Paulo state, founded in 2024.
