While Abruptum is classified as a black metal/dark ambient band, the band took a different approach to their music. They did not create really any structured songs and mostly just made noise. Earlier material had shorter songs but their later releases typically included one or two tracks with more than forty minutes of music. They primarily used drums, guitars, bass, keyboards and other various instruments but what stood out even more was the screaming as the band supposedly tortured and cut each other during their recordings. Whether this is true or not has never really been verified.
