The Skinny on Sumi Jo

"On Jan. 12, at Sherman Clay Pianos, Jo told an audience of close to 100 that she doesn’t eat any chocolate, cold foods, or deep-fried foods. That means no ice cream, milkshakes, refrigerated juices, deli meats, seafood cocktails, or salads. Absolutely no smoking or drinking alcohol is allowed because they would instantly kill her voice. Jo knows six languages including Korean, German, French, Italian, Russian, and English. Many of her teachers were Italians. She has studied music since she was 4 years old." [Source]
