As part of the Echo Reads... sereies, Echo Theatre will present The Piano Teacher, a play about an elderly widow who reminisces about the children she taught long ago as a piano instructor. One day, she finds herself compelled to call her old students -- but is it out of loneliness or some other, darker need? As Mrs. K discovers, it may not be what we cannot know that troubles us the most; it may be what we cannot bear to know.
