BBC Radiophonic Workshop – 21 is a compilation by the
BBC Radiophonic Workshop to celebrate their 21st anniversary in 1979. It was compiled as an overview of their work both old and new, showcasing the changes in the Workshop as they developed from backroom
sound effects suppliers for
BBC Radio to full-fledged in-house music composers for the whole of the corporation. It demonstrates the move from the
musique concrète and tape-manipulation techniques used in the early days, to the
synthesiser works of the 1970s. The first side of the album consisted of material from 1958 to 1971, covering their early work creating jingles, sound-effects and some incidental music. This side includes the first material by Workshop founder
Desmond Briscoe to be commercially released, as well as sound effects from The Goon Show, Maddalena Fagandini's
interval signal that later became "
Time Beat", some of
Delia Derbyshire's experimental work and the
pilot episode version of the
Doctor Who theme music. The second side of the record covered the period between 1971 and 1979, including
Richard Yeoman-Clark material from popular BBC series Blake's 7 and
Peter Howell's vocoder heavy "Greenwich Chorus" theme for The Body in Question. It was reissued on CD by
Silva Screen Records on 22 April 2016.[1]
