[1][2][3][4] The soundtrack, commissioned in 2013 by the Berwick Film and Media Arts Festival,[5] was composed by the Sunderland band Field Music.

The composition is the first of their works to feature pianist Andrew Moore since 2007's Tones of Town.

After touring the film accompanied by the band playing the soundtrack live around the UK, the composition was recorded and released firstly on vinyl for Record Store Day 2015 (limited to 750 copies[6]), and then digitally in July 2015.

Though a niche release commercially, the soundtrack was well received by some critics, with several praising the band's ability to evoke "...an oddly aquatic ambience...the percussive delicacy evocative of the lapping tide, the idiosyncratic shifting of pace signalling the unease of the environment".

[12] The Scotsman praised the touring performance of the soundtrack, giving it four stars (out of five) and again noting the "complementary score of plangent guitar, electro jazz keyboards and a slow martial beat to match the hypnotic footage of bobbing buoys and silvery shoals caught in the nets.
