From the opening note through the final encore, Miss Wang never failed to impress. Her passion and intensity flow through the music with incandescent brilliance. I too was very disappointed with the audience members that just could not allow one singe phrase of music to pass without being interrupted by talking, cell phones, water bottles, and of course, coughing. Please UMS, try to implement something that discourages those mindless people from ruining it for the rest of us. I paid to hear the artist, not them.
