With her triple live album Before The Dawn arriving this Friday (November 25th), Kate Bush has unveiled a special piece of film to accompany the recently unveiled live version of 'And Dream Of Sheep'.

The clip features Bush adrift while wearing a lifesaving jacket - a mise-en-scène that gains a whole new dimension when we learn she actually performed the vocal live while lying in a huge water tank at Pinewood Studios.

"She spent so long in the water during the first day of filming that she contracted mild hypothermia," it is explained in the video's accompanying text. "She recovered after a day off and carried on filming. Everyone agreed it had added to the authenticity of the performance."

Needless to say, the audio/video combination is breathtaking; watch it below.
