A true pioneer in audio exploration and psycho-acoustics, Delia Derbyshire conceived one of the most familiar compositions in science fiction, the Doctor Who theme, while working in a BBC basement. Her soundscapes felt like they connected to another realm. Kicking off with the discovery of 267 tapes in an attic, along with a treasure trove of journals hidden in her childhood bedroom, this film tunes in to Derbyshire’s frequency; that of a life-long non-conformist, whose peals of laughter in an archive interview tickle with delight and eccentricity. Featuring a rich archive, interviews, fictional embodiment and Cosey Fanni Tutti’s psycho-sonic channelling, director Caroline Catz traces acoustic pathways on her archeological dig into Derbyshire’s resonant life.

Trivia, insights & behind the scenes
Derbyshire created the Doctor Who theme before synthesizers existed—she spliced tape by hand, note by note, sometimes using her own voice slowed to a growl.
The BBC denied her composer credit on Doctor Who, listing 'Ron Grainer and the BBC Radiophonic Workshop' instead. She didn't fight it. She just kept building universes in the dark.
