Immolation is a death metal band from Yonkers, New York. They were formed in 1986 as Rigor Mortis. The name was changed to Immolation in late 1987, between the "Warriors of Doom" demo which was done as Rigor Mortis and "Demo I" which was done as Immolation. The band recorded 4 songs on the "Demo II" 1989 sessions, but only 3 were finally released: "Internal decadence", "Burial Ground" and "Despondent Souls". The remaining song is "Infectious Blood" (later re-named "Fall in Disease" on the "Dawn of Possession" Album).
