Born in Johannesburg, Mahlangu was educated at the Katlehong Art Centre, where he concentrated on sculpture under the tutelage of Stanley Nkosi, and painting with Rose Shakanovsky.

Ndebele artist Mahlangu’s works depict a dream world with its roots in Ndebele myths; Ndebele designs taught to him by the elder women; as well as Egyptian hieroglyphics, drums, and calabashes - all of which form recurring motifs in Mahlangu’s works. These he combines with figures, often therianthropic, placed within surreal landscapes.

"My imagery draws on traditional practices inspired by my grandfather, who introduced me to the legends and symbolism of animals and ancestor sacrifice."
