Blood was formed by Bernd Eisenstein, Taki, Geer and Radtke in March 1986 in Germany. They recorded 3 demos during this time. During 1987 the band evolved and their new songs were much more structured and began to resemble the early recordings of perhaps their most prominent influence, Napalm Death, who had pioneered a similar style of deathgrind with their own demos. The fourth Blood demo, ?Heinous Noise,? was released in October of 1987. With an updated lineup, Blood recorded their fifth demo, ?Spasmo Paralytic Dreams,? in February of 1988. For their sixth demo tape, vocals were performed by Chuck from Deathcore, and Destroyer Eisen himself. Following releasing these fourth, fifth, and sixth demos, Blood caught the attention of Wild Rags Records, who released their infamous debut album, ?Impulse to Destroy? . Originally released by the band on a very limited number of cassettes, these demos chronicle the development of a sound that is still revered as one of the most savage in the deathgrind subgenre.
