One of the great iconoclasts within modern American music, Canadian-born composer Henry Brant is a radical figure whose work is impossible to classify. Born in Montreal, Brant began composing at the age of eight and studied at McGill University beginning in his 16th year.

Brant continued along these lines, producing works of gigantic proportions, for example his Orbits (1979), scored for soprano, organ, and 80 trombones. After 1980, another aspect of Ives' influence opened up new vistas in...
