“I Love a Piano” is a nostalgic musical journey that spans seven decades of American history as seen through the eyes of Irving Berlin. The show tracks the life of a piano with one sour key through four generations of singers and dancers who perform with and around it. With six actors and more than 60 of Berlin’s enduring and popular favorites, this spectacular show captures the spirit of America from the Ragtime rhythms of the early 20th century through the swinging sophistication of the 1920s and ‘30s.
