The final day of Alcatraz Open Air 2025 saw the Swamp Stage immerse itself in the darker corners of metal. From the haunting intensity of Gaerea and the uncompromising black metal of Tsjuder to the progressive soundscapes of Borknagar, the legendary presence of Emperor, and the ritualistic atmosphere of Rotting Christ, the stage offered a compelling journey through some of the genre’s finest names.
