In my library: Hélène GrimaudGreat musicians are often interesting people, some with unusual hobbies. Even so, Hélène Grimaud is the rare pianist who spends her free time running with wolves. At her farm in upstate New York, about an hour from Manhattan, the Frenchborn animal lover oversees the Wolf Conservation Center, where she's considered a member of the pack. Never mind those steely jaws: "I'm fairly fatalistic," she says. "I think if something's going to happen, it will happen." Right now, she's touring on behalf of her new CD recordings of Brahms Piano Concertos 1 and 2-works written 22 years apart. It's a journey that will take her to Carnegie Hall on Dec. 6, when she performs with the Philadelphia Orchestra. Here are four books that are close to her heart.
