In the first of his two concerts at the 2011 Tanglewood Festival, Christoph von Dohnányi accompanied Yo-Yo Ma in the cellist’s annual appearance at the festival, with the concerto by Robert Schumann that both musicians have championed throughout their careers (Dohnanyi and the BSO accompanied Alban Gerhardt’s performance in 2005). Bookending the concerto were two symphonies with the potential for lean classicism which is the conductor’s hallmark: Prokofiev’s tribute to the age of Haydn and Brahms’s long-gestated successor to Beethoven with a work that obliquely honours the memory of his friend Schumann.
