Primitive Calculators are an Australian post-punk band formed in Melbourne in 1978, known for their minimalist approach to instrumentation and haunting, angular compositions that influenced the post-punk and indie rock movements. The band's sparse, hypnotic sound and cerebral lyrics established them as key figures in the Australian underground music scene during the late 1970s and early 1980s. With their cult status and pioneering artistic vision, Primitive Calculators remain influential to contemporary alternative and experimental musicians worldwide.
