Kosmische Keuterboeren plays psychedelic 'brol noise' which combines kraut rock, doom metal, freak folk, psychedelica, and recently lo fi techo/dubstep. The band has two members i.e. Jeroenymous of Blodklod and the legendary Mollenhauer (r.i.p.), one of the many bands of the Belgian Funeral Folk label, and Evil Fons, mostly know from Penguins Know Why. Sometimes they gather with Hellvete.
