Pioneers of Sound is a short documentary that looks at the history and influence of the BBC Radiophonic Workshop.
The BBC Radiophonic Workshop was originally created in 1958, to create sound effects and music for radio. It was closed in March 1998, because other alternatives had become available.
Since then, several of the original members of the BBC Radiophonic Workshop have regrouped as an electronic music group, Radiophonic Workshop.
