Scottish percussionist Evelyn Glennie. She's one of the world's few classical percussion soloists. And she plays with orchestras worldwide. But instead of hearing the music, she feels it. Glennie is deaf, and has been since the age of 12. She's made several solo albums, and several years ago wrote her autobiography, Good Vibrations (Hutchison Publishers, London). Glennie performs at the Academy of Music in Philadelphia Dec 15 and 16. (Interview by Marty Moss-Coane)
