'The Midwich Cuckoos' is based on the 1957 science fiction novel by John Wyndham, and tells the story of an English village where the women become mysteriously pregnant. Hannah Peel's score is described as a unique and intricately produced soundscape, working in harmony with the sound design of Sky's adaptation. With analogue synthesisers recreating the horror of the 'Hive Mind', tape manipulations, drones, woodwind and melodies echoing the song of the cuckoo bird, Peel creates a score that perfectly balances the organic instrumentations and melodies, juxtaposed with an increasingly dark electronic 'invasion'. Peel explains, 'creating the score was a constant endeavour to find the balance between darkness and light, fear and beauty. It was a very fine and intricate equilibrium between the normal sunlit logical world as we know it, and a subversive unfamiliar musical language'.
