In celebration of the Pierre Boulez centenary, Tamara Stefanovich performs the composer’s Second Piano Sonata of 1948, one of his defining early works. Known internationally for her interpretations of modernist and contemporary repertoire, the pianist pairs it with a selection of avant­-garde experiments on the sonata form from the early 20th century—including Scriabin’s mystic “Black Mass,” written in 1911, Busoni’s fantastical, atonal Sonatina seconda, and youthful works by Alban Berg, and Dmitri Shostakovich.
