It is a gravity-defying spectacle which gives a whole new meaning to the term 'rock opera'.
These aerial ballet dancers provide the daredevil backdrop to a new opera being screened simultaneously in five different countries.
In one of the most ambitious arts projects ever put together, synchronised productions of St Kilda: A European Opera – linked by satellite broadcast – will delight audiences in Germany, Belgium, France, Austria and Scotland.
The £1.8million, 82-minute show tells the story of the Outer Hebridean island of St Kilda, whose last inhabitants were taken from their remote homes 75 years ago.
The opera, performed in Gaelic, is set against a film of dancers gyrating on ropes suspended from the cliffs.
The footage was shot by awardwinning cameraman Keith Partridge, of Touching The Void fame.
The libretto includes Gaelic songs performed on St Kilda and in Stornoway, on the isle of Lewis.
