This almost century-old instrument, known affectionately as the Mighty Wurli, rises dramatically from beneath the stage in the Addison Theatre to charm audiences with its unique sound. It was built in New York by the Rudolph Wurlitzer Music Corporation and was originally designed to accompany silent films. Thanks to almost 1000 pipes and 47km of wiring, it can replicate the sound of a full orchestra (including strings, brass, woodwinds and percussion) as well as produce theatrical sound effects like whistles, sleigh bells and thunder.
