Pianist Leon Fleisher was just 34 years old when he first realized something was terribly wrong. Suddenly and without warning, the fourth and fifth fingers of his right hand began to curl under involuntarily whenever he played the piano. The debilitating condition ended one of the most celebrated piano careers of the mid 20th century. But it also marked the beginning of one of the century’s most inspiring musical stories. Fleisher, now 82, never gave up. He took up residence at the Peabody Conservatory of Music in Baltimore and became one of the world’s most important piano professors. He learned to conduct, and after a 30-year search for a cure, he was diagnosed at age 66 with focal dystonia and cured with experimental Botox injections. Fleisher will be in Nashville this weekend to conduct Brahms’ Symphony No. 4 with the Vanderbilt Orchestra. He will also be available to sign his new book, My Nine Lives: A Memoir of Many Careers in Music, which chronicles his life’s extraordinary musical journey.
