Yom Kippur, the Day of Atonement, begins at sundown. To mark the occasion, the holiest day on the Jewish calendar, I’ll present Jacob Weinberg’s String Quartet, Op. 55, which incorporates melodies for the High Holy Days; Enest Bloch’s moving “Israel Symphony;” Joseph Joachim’s “Hebrew Melodies;” David Stock’s “Yizkor;” and Emil Nikolaus von Reznicek’s “Symphonic Variations on ‘Kol Nidre.’” It all begins at 2 p.m. EDT, on WWFM – The Classical Network and wwfm.org. G’mar Hativa Tova.
