Formed in 2017 in Granada, Oniric Prison stormed onto the scene with a forceful blend of thrash and hardcore. Their self-titled debut, released in 2019, was a bold statement that earned them a place in the underground scene. After the pandemic and lineup changes, they returned with ‘Slumber,’ an EP that reflects the intensity and aggression of their sound. Oniric Prison promises to ignite a fierce moshpit at Rock Imperium Festival 2025.
