The BBC showed a terrific documentary about Delia Derbyshire and the radio-phonic workshop (1960s). The workshop was a technical research laboratory at the BBC that was tasked with using machine and synthesised sounds in new ways.
Delia Derbyshire was one of the workshop’s most significant personalities and is credited with having made a number of key developments in tape-loops, synthesised sounds and electronic music composition, Nowadays, she is best remembered as the composer of the Dr Who theme music, and as a pioneer of electronic dance music…there’s an element of retro-fitting going on here, but she is a very important figure.
