dark gothic rock with female lead vocals and forceful male rock responses, 1910s wartime atmosphere, slow marching 4/4 groove around 78 BPM, distorted baritone guitars, tolling piano, martial snare, low strings, brass-like synth swells, verses restrained and tense, pre-choruses building with toms, choruses exploding into a wide anthemic wall, dramatic call-and-response between female and male voices, raw disciplined delivery, cinematic but gritty mix, close vocal in verses and doubled gang vocals on the final chorus
