William Alexander Galison, born February 19, 1958 in New York City, is an American harmonica player. He started on piano as a child but switched to guitar at eight, having been inspired by the Beatles. Galison's love for jazz led him to Berklee College of Music, where he chose the harmonica for its portability. Galison toured Europe with Billy Leadbelly and performed at venues like The Village Gate and The Blue Note in New York. He collaborated with artists including Carly Simon, Barbra Streisand, and Chaka Khan. His work is featured on soundtracks for films like The Untouchables and Bagdad Café, as well as the Sesame Street theme. In 2004, Galison released "Got You on My Mind" with jazz singer Madeleine Peyroux. He has been recognized for his originality in the harmonica genre.
