Philip Glass has become an iconic figure in American music. His works are often inspired by collaborations with other leading musicians, and the proposal of an “American Four Seasons” by the violinist Robert McDuffie to reflect Vivaldi’s famous masterpiece resulted in a concerto which evokes the Baroque spirit of early 18th-century violin tradition. With the Concerto’s range of moods, listeners are invited to decide for themselves which season the music evokes. The Violin Sonata sees Glass’s melodic and harmonic language haunted by the ghosts of Brahms, Fauré and Franck, “the meditativeness of this piece bringing a unique energy” for award-winning violinist Piotr Plawner.
