Systematics were one of the Sydney post-punk "little bands" from the early to mid 1980s. They released most of their material on the famous M-Squared records (home also to Scattered Order). See also Severed Heads, Pulp Baby and Patrick Gibson. More about the "little bands" can be read at Phil Turnbull's site 'No Night Sweats' and 'Inner City Sound'. See also The Systematics.
