Acclaimed British violist Helen Callus not only plumbs the potential of an instrument beloved for its eloquence, she also seeks out new ways to expand its reach. This week on Saint Paul Sunday she joins pianist Phillip Bush for music that explores the viola to the fullest. Along with music of Brahms and Prokofiev, she brings us music of two little-known composers with whom she shares a great deal.

Female at a time when British composers were almost exclusively men, Rebecca Clarke and Pamela Harrison each carved out wonderful new terrain for the viola. Ms. Callus takes us through it with the passion of a fellow-traveler.
