Inventions for Radio were a series of four radio broadcasts that first aired on BBC's Third Programme in 1964 and 1965. The broadcasts, titled The Dreams, Amor Dei, The After-Life and The Evenings of Certain Lives, were created by Delia Derbyshire of the BBC Radiophonic Workshop and Barry Bermange. Each of the individual broadcasts consists of a sound collage of electronic music and effects combined with spliced and remixed dialogue from interviews with everyday people. Each "invention" addressed an individual theme—dreams, the nature and existence of God, life after death, and ageing.
The soundscapes created by Derbyshire for Inventions for Radio have been described as "unsettling, dreamlike, and mesmerizing." Despite her role in composing the soundscapes, mixing, and editing the work, Derbyshire's contributions to Inventions for Radio were rarely acknowledged, instead being credited to Bermange and the Radiophonic Workshop.
