The Jewish High Holy Days are a period of reflection, ten days of awe and repentance. Tune in for ruminative music by Jacob Weinberg (his String Quartet No. 2 in three movements – “Rosh Hashana,” “Yom Kippur,” and “Sukkot”) and Emil Nikolaus von Reznicek (the Symphonic Variations on Kol Nidre); also, a reverential setting of Max Janowski’s Avinu Malkeynu. The mood is meditative for Yom Kippur, this Sunday at 10 pm.
