Three approaches drive Marc's sculpture: structural balance, composition and texture. The first two stem from his background as an architect, the third from his fascination with the way metals respond to heat, not only in shaping but in the colour and surface quality which result from the oxyacetylene flame and form the applied welded texture. Most often he has used found objects, scrap and new steel and copper, joined them together into personally evocative and meaningful pieces.
He has worked on his sculpture in London, Johannesburg, Toronto and Chatelus Malvalieux, France in the studio of Paul Flury Sculptor. His work has been exhibited in the UK in Hampstead; the Coningsby Gallery, London as part of the Urbanite Collective; and the Bath Society of Artists. In Toronto he has exhibited at the Pentimento Gallery and GAS (Gerrard Art Space). His work is in numerous private collections in Toronto, Montreal, Vermont and London, England.
