Violinist Mark O’Connor is one of those musicians who come along maybe once or twice in a generation. They glide effortlessly from one genre to another with complete command over every aspect of their art. O’Connor has studied under Stephane Grappelli, one of the world’s greatest improvisers on the violin, yet at the same time, he has written and performed orchestral scores with the likes of Yo-Yo Ma and Edgar Meyer.
