Okrütnik is a formation founded in May 2018 in Kotlina on the initiative of Michał, Grzegorz, Szymon and Mateusz. At the beginning of June, Eryk joined the line-up. The sound of Okrütnik can be qualified as broadly understood heavy metal with thras and black metal elements. The lyrics create a unique message, characterized by references to poetry, human and world negation, occultism and nihilistic beliefs. Every day Okrütnik operates at the House of Culture in Kotlina.
