SPK

SPK are an industrial music group formed in Sydney, Australia in 1978. They are fronted by mainstay member, Graeme Revell, on keyboards and percussion. In 1980 the group traveled to the United Kingdom where they recorded their debut studio album, Information Overload Unit (1981).

According to Australian rock music historian Ian McFarlane, SPK were "at the forefront of the local post-punk, electronic/experimental movement of the late 1970s ... [their] music progressed from discordant, industrial-strength metal noise to sophisticated and restrained dance-rock with strange attributes".

In 1983, Sinan Leong joined on lead vocals, after which the group pursued a more commercial industrial dance style with the single "Junk Funk" and their third studio album, Machine Age Voodoo (1984). The group disbanded in 1988. Two years later Revell and Leong relocated to the United States, where Revell worked as a Hollywood film score composer.

In 2025, Revell reactivated SPK, performing two live shows in Europe with his son Robert. A "new entity", named SPKtR, is expected to begin touring in 2026.
