Malicious Onslaught formed in 1986 in Stony Point located in Rockland County, NY by brothers, vocalist/bassist Ted Hanauer and guitarist/vocalist Robert Hanauer. They had a death/thrash metal sound and one of their influences was Slayer. As time went by, they leaned more towards the death metal side. They released a slew of demos and only two full-length albums. Ted Hanauer was 12 years old on the first demo released in 1986.
