Hulder is a one-woman black metal band founded in 2018 by Belgian-born multi-instrumentalist and vocalist Marliese Beeuwsaert, also known as Marz Riesterer, who performs all instruments and vocals. Inspired by her love of Scandinavian folklore and traditional Belgian tales, the band's sound blends classic black metal with emotional depth and a unique atmosphere. The name "Hulder" itself refers to a seductive forest spirit from Scandinavian mythology, known for her beautiful appearance and a cow's or fox's tail.
