The trio had been touring in Europe and Asia, performing various works by Mozart, Beethoven, Chopin, Brahms, Schumann, Schubert, Tchaikovsky, Anton Areński, Sergey Taneyev and other composers. After Michal immigrated to the United States in 1927, Maria continued playing in a duo with Kazimierz. The group reunited again in 1945 with a half-sister Wanda Wiłkomirska.
