Onhou was founded in 2016 and consists of previous and current members of Ravenwiek, Grinding Halt and Ortega. Rooted in Groningen, Onhou embodies their northern heritage by mixing desolate sludgy Doom riffs with miserable Post-metal atmospheres, embracing the sinister history of the soil that made them. After releasing their first EP Onhou in 2018 on Tartarus Records and their first full length Endling on Lay Bare Recordings and Tartarus Records in 2019, Onhou established themselves as one of the heaviest bands in the northern Dutch territories.
