Prisoners in Nazi concentration camps made music; now it’s being discovered and performed. More than 6 million people, most of them Jews, died in the Holocaust. The music they wrote as a temporary escape, however, did not die with them, thanks in part to the efforts of Francesco Lotoro. An Italian composer and pianist, Lotoro has spent 30 years recovering, performing, and in some cases, finishing pieces of work composed in captivity. Nearly 75 years after the camps were liberated, Francesco Lotoro is on a remarkable rescue mission, reviving music such as the one created by a young Jewish woman in a Nazi concentration camp in 1944.
