Shriver Hall produces a top-notch classical series, with many of the legendary performers who are playing this season at Carnegie Hall. And the prices — I have sticker shock in reverse. Les Violons du Roy, the renowned Quebec baroque ensemble, is discounted for $25. Les Violons du Roy is playing Carnegie Hall this March for $63 to $85. The brilliant pianist Richard Goode is playing Shriver Hall (Mozart and Chopin) for a modest $38. Richard Goode will play at Carnegie Hall in April, and comparable tickets range from $67 to $99. This season, Angela Hewitt, the marvelous interpreter of early music, is playing Rameau at Shriver in May. I'm tempted to take the train to Baltimore to hear her. She is not scheduled to play in New York this season.
