Trombonist Christopher Dudley grew up in State College, and is now Principal Trombone of the Baltimore Symphony. He plays some jazz and rock, as well as classical music, and recently played on a recording by a world-famous rock star. His mother, Dolores Dudley Simpson, will be in the audience as he returns home to be guest soloist with the State College Municipal Band on Mother's Day. WPSU's Kristine Allen has the story.
