Near-infinite doom, My Dying Bride ground up by sort of gravelly Entombed tones, death vocals, and Neurosis chill-outs added, just to make you extra sad.
From delicate piano serenades to galloping metal to broody Goth metal, Nicodemus ooze style, good musicianship, and the dynamics most bands had to build up to.
More like prog rock with dark melodies, with songs that are essentially energetic and full band, lots of moody pop, not a lot of long, boring passages.
