Moonlight Sorcery has been revealed as the next exclusive act to perform at the 2025 edition of Fortress Festival, scheduled for May 31 - June 1 at Scarborough Spa in Scarborough, North Yorkshire, UK.

This will be an international exclusive set, a UK and international debut and the only show outside of Finland until at least 2026 from the Finnish band.
