Henri Chopin was an avant-garde artist, poet and musician, other than a painter, graphic artist and designer, teacher, typographer, independent publisher, film-maker, broadcaster and arts promoter. Known primarily as a concrete and sound poet, he created a large body of pioneering recordings using early tape recorders, studio technologies and the sounds of the manipulated human voice. His emphasis on sound is a reminder that language stems as much from oral traditions as from classic literature, of the relationship of balance between order and chaos.
