Dissonance (2015)

A genius musician lives a lonely life in a surreal, floating world. He plays the piano every day in a gigantic concert hall, but there is nobody to listen. One day his animated world collapses and reality breaks out. The film seamlessly transforms from an animation into a live action drama, reflecting the journey from his psychotic mind into the real world. He only has one wish: To play for his daughter, which he is not allowed to visit.
