Nihilist Assault Group began in 1984. Members at that time are unknown, although the line-up did include a member of The New Blockaders. Nothing was heard of them until 2005 when they appeared at the No Fun Festival in New York. The line-up for that show included members of TNB, Prurient and Emil Beaulieau. Recent releases have included input from members of TNB, Putrefier, Cheapmachines, Snotnosed and Blue Sabbath Black Cheer.
NB: This (original) Nihilist Assault Group has nothing to do with other groups or organizations (or song titles!) who are using the name.
