That video at the start was - disconcerting.
Girl playing piano, doing a great job.. then a second piano joins in.

Sure it was probably MIDI or a sequencer, re-playing the accompanying section. It was just - jarring. Like a street busker with a personal amp, suddenly being accompanied by an invisible chorus and orchestra.
