Three weeks of concerts continue at Library Hall, and Paul Hersh again is the artist in residence. Soprano Christine Klemperer performs in Schubert’s The Shepherd on the Rock. Hersh performs Beethoven’s Sonata in C Minor, Op. 111, and violinist Joseph Genualdi makes his debut Sept. 2 in Schubert’s Octet, Op. 166 and performs Vivaldi’s The Four Seasons with orchestra. This is also the first year of New York State Council on the Arts support.
