Video works inspired by fundamental human experiences such as birth, death and aspects of consciousness.
Viola has a deep interest in mystical traditions – especially Zen Buddhism, Christian mysticism and Islamic Sufism – evident in the transcendental quality of his work. His videos often have a painterly quality, drawing on Western medieval and renaissance devotional art in their aesthetic.
An ongoing theme is dualism – the idea that you can't understand what you're looking at unless you know its opposite. As such Viola likes to explore contrasting themes, such as life and death, light and dark, stressed and calm, loud and quiet.
