Ahead of the 100th anniversary of the break out of World War I, the conductor Leon Botstein and this ensemble present the program "Forged From Fire." The evening opens with a work by Reger that expressed German imperialist ambitions. It will be followed by pieces by Ives and Szymanowski (his Third Symphony) that convey new currents of awareness in America and Poland, and Bloch's "Israel" Symphony, which captures new Jewish nationalism during this fraught period. Mr. Botstein will lead a preconcert Q.&A. at 7 p.m.
