Davis Silis brings Nick Mulvey and his band together with a big bunch of dancers in a joyful jam for Mountains To Move.

With choreography by Jonny Vieco, Silis turns his dancers into a happy gang who counterpoint the conventional band set-up of Mulvey and company with their apparent freestyle movement. The bright and breezy atmosphere is aided by the setting, the grounds of an old cigarette factory in High Wycombe.

"Crazy place, that's sort of been taken over by skaters," says Silis, who adds that although the principle of the dancers' movement were all rehearsed, new details were added in every take to add a layer of unpredictability - which posed a challenge to editor Owen O'Sullivan.

"Almost all the choreography was different in each take, so no two shots were ever the same. There were a few simple principles for how the movement needed to work, but once the camera started rolling, one dancer would lead and the others followed (for the sync stuff), which then just unfolded into the free-for-all toward the end. So the fact that Owen could make it link together that fluidity was all down to him!"
