Kathryn Lewek is an American soprano, who, this summer, has been singing at the Salzburg Festival. That’s where Jay caught up with her. They talk about her life, and voice, and other interesting things. “Katie” is especially known for portraying the Queen of the Night, in Mozart’s “Magic Flute.” Mozart “is my sugar daddy,” she says. “He’s given me everything I’ve got. He bought my car, he bought my house. He feeds my kids . . .” A delightful woman, and a brilliant singer, Kathryn Lewek.
