Anna Levy and Yarilo Music Society extends a hearty invitation to its annual concert. The concert is a collage of three pieces: Simeon Ten Holt’s Canto Ostinato, Colin MacDonald’s Firewalk, and Liubomir Melnyk’s Fountains; preceding and ending the program will be the second of Erik Satie’s Pieces froids, Danses a travers, an unmeasured work that functions as an introduction and a coda in the context of the program.
