Salisbury met Barrow when they had both begun playing football for a five-a-side league on weekends. However, it wasn't until five years had passed that they discovered each other's profession and decided to begin working together. Salisbury then began orchestrating string arrangements for bands on Barrow's own Invada Records. It was through this that he began working with artists on the Bristol music scene, including Malachai, for whom he arranged and co-wrote some of the material on their sophomore effort, Return to the Ugly Side. He also worked on Boca 45's Vertigo Sounds and the Beekeepers' debut, Apiculture. Barrow had then begun working as a music supervisor for the Banksy film Exit Through the Gift Shop, and eventually brought in Salisbury -- this would be the pair's first partnership in working on film music together.
In 2012, the duo worked together on their film score for the sci-fi thriller Dredd. Although their material was declined by the studio, Salisbury and Barrow decided to release their efforts anyway and put out the Drokk: Music Inspired by Mega-City One album via Invada in 2012. That year also saw Salisbury compose the music for Beyoncé's autobiographical film Life Is But a Dream. In 2014, Salisbury and Barrow were recruited by author/screenwriter Alex Garland to provide the score for his directorial debut, Ex Machina. The pair delivered a highly atmospheric, percussion-less, and minimal yet hefty film score, which earned them the award for Best Original Score at the 2016 Ivor Novello Awards. They worked with Garland again in 2018, scoring his second movie, Annihilation. ~ Rob Wacey, Rovi
