This weekend mark's our first birthday, and it occurred to us that we've been rather remiss in our formative year in not having featured a music supervisor. So we decided to put that right by speaking to Sarah Bridge, who came highly recommended by one of our previous guests, the Oscar winning John Ridley.

As well collaborating with John on Sky Atlantic's TV series Guerrilla, Sarah has worked on a host of critically acclaimed productions including X + Y, The Sense Of An Ending and The Theory Of Everything. The latter was scored by one of her idols, Jóhann Jóhannsson.

This episode features examples of his score, not to mention music by Max Richter, Femi Kuti, Keaton Henson and Irma Thomas.

But we began by learning about the myriad facets to Sarah's role in the movie-making process.
