Informed by 1980s American culture, Rennie started his practice as a teenage graffiti artist, finding his voice on the surfaces of Melbourne city’s buildings, trains and laneways. Since his first solo shows in 2009, Rennie has staged seventeen one-person exhibitions of his work in Australia, Indonesia, the United States and France, and participated in numerous group exhibitions worldwide, including Personal Structures, a Venice Biennale 2017 collateral exhibition.
