Spontaneous Combustion embraces the holistic vision of one of Aotearoa New Zealand’s most provocative artists and thinkers: the unity of the natural environment and the human imagination, the energy, rhythm and textures of the physical world expressed in clay, words, and music. The film celebrates the legacy of Barry Brickell (1935-2016) and the realisation of his extraordinary dream, Driving Creek Railway: a productive pottery with numerous kilns, a bush railway, a native bird and bush sanctuary and a lively creative hub drawing artists from around the globe.
