Like many working mothers, Clara Schumann worried about her children when she wasn't there. "Give my little ones, for whom I yearn so much, 1000 kisses," she wrote while away on concert tour. Clara Schumann was one of the top pianists of her day, a much sought-after concert artist. She was also the family breadwinner during her husband Robert's long battle with mental illness. In today's show, a piano concerto by Clara Schumann, in honor of Mother's Day.
