The Primitive Calculators are an Australian post-punk band, formed in Melbourne, Victoria in 1978. Described by British critic Everett True as sounding like "a very aggressive Suicide", the band is known for its mix of harsh guitar noise, fast and repetitive drum machine beats, and abrasive synthesizers. Along with fellow Melbourne act Whirlywirld, the Primitive Calculators played a leading role in founding the experimental Little Band Scene in the late 1970s, wherein both bands and numerous other acts formed large numbers of short-lived bands by frequently swapping members and inviting non-musicians to join in at live shows.
