 Footage from the final rehearsal at Campfield Market Hall in Manchester for Biophilia world premiere at the Manchester International Festival is shown, with the Sharpsichord arriving at the venue.Some of other instruments used during the show are presented, like MIDI-controlled Tesla coil, invented by Nikola Tesla, and a gravity-harnessed pendulum harp invented by Andy Cavatorta of the Massachusetts Institute of Technology.Cavatorta recounts how Björk declared to him that she wanted nature to appear like "some sort of a rock star on stage", and tells that the first prototypes of the instruments were filmed and shown to Björk before she approved the final result.
