I have always been fascinated by the way music can completely change the way you watch film - and how you feel as you watch the images.

For the last year or so I have been collecting all sorts of footage of people dancing that I found in the BBC archives. In all I gathered over two thousand shots culled from all kinds of programmes. I then cut some of them together to music by the wonderful 70s German band Neu.

I think it gives a sense that we are all together in the dance.

I then took exactly the same sequence of images - I haven't altered even a frame - and put them to a montage of some very different music. There are all sorts of songs and pieces in there - but it owes a great deal to the great romantic musical genius of our age - Burial.

I think that this other version leads you to look at the people dancing in a very different way. The feeling it evokes is how separate we are - and how isolated we sometimes are from one another.
