Canvas (2000), commissioned by the College Band Directors National Association, was completed in September of 2000. the piece is dedicated to Mr. Walker's parents. Its three movements, called "Extracts, " offer the possibility of each being performed separately. The first Extract, subtitled "Landscape," is a purely instrumental movement that is arch-like in its formal construction. The second Extract, "Commentary," introduces a conversational element that ranges from the philosophical, through points of whimsy, to a declaration of social awareness from the five speaking voices employed. The text, is Walker's. It concludes with a quote from a popular standard. The third Extract, "Psalm, 121," utilizes a chorus with two brief tenor solos in a setting of the King James Version of this text.
