The crash of the seas, the crumbling of city walls and a glimpse of the heavens: all come together in the 2025 First Night. There’s a Scottish sound-picture from Mendelssohn and cool Nordic grandeur from Sibelius. Errollyn Wallen harnesses primal forces in her colourful new orchestral commission, while visions from the Book of Revelation are the starting point for Vaughan Williams’s Sancta civitas.
