I've been a fan for a long time and have been to one of his shows. I appreciate his love for beautiful music and he has found a way to keep it alive. I believe his success lies in bringing classical/semi-classical music to the "common folk" where it had previously been reserved for the "black tie only" set. Of course this is not the only music he plays. But attending a concert featuring Viennesse music in casual clothing and dancing in the aisles would be an outrage to the traditional classical crowd who often criticize him.
The music has always been out there but he has found a way to bring it to the masses in a way that gets their attention, inviting them in instead of shutting them out (with a lot of help from PBS). I am grateful he's done this.
