One the world’s few acknowledged virtuosos of the viola, Garth Knox is known for playing some of the most demanding music written for that instrument with elegance and dash. On November 14, he’ll also perform pieces for the viola d’amore, a period instrument with resonating strings mounted beneath its bowed ones. The program ranges from Tobias Hume’s 1605 Pavane to one of Knox’s own compositions from his CD Viola Spaces. The evening’s highlight will be the world premiere of a new piece for viola d’amore and electronics by English composer James Dillon under a commission from the French band Art Zoyd. The artist will give a talk before the concert.
