A few days before Pierre Boulez’s 100th birthday, Matthias Pintscher and the Boulez Ensemble celebrate the composer, who passed away in 2016, with a perfor­ mance of sur Incises, his last major ensemble work. The program also includes Debussy’s Sonata for Flute, Viola, and Harp as well as Pintscher’s own beyond II (bridge over troubled water). Scored for the same combina­ tion of three instruments, it received its premiere as part of the digital Festival of New Music in the summer of 2020 and is now heard live at the Pierre Boulez Saal for the first time.
