“Delia Ann Derbyshire (5 May 1937 – 3 July 2001[1]) was an English musician and composer of electronic music[2] and musique concrète. She is best known for her electronic realisation of Ron Grainer’s theme music to the British science fiction television series Doctor Who and for her work with the BBC Radiophonic Workshop.” – Wikipedia.
“Derbyshire was one of the most pioneering electronic musicians Britain has produced, and for many years she was an integral part of the BBC Radiophonic Workshop. Popular culture will mostly recognise her for producing the first version of the Doctor Who theme, but Ziwzih Ziwzih OO-OO-OO was made for a different sci-fi programme – Out of the Unknown, which ran from 1965 to 1971. Ziwzih Ziwzih OO-OO-OO featured in an episode called The Prophet, adapted from an Isaac Asimov story, which was broadcast in January 1967. Sadly the BBC junked it from the archives. The track itself is short, less than two minutes, but would have been made with no sampling, no computers, nothing except tape and primitive electronic sound generators. Yet there is something about it that still sounds futuristic and otherworldly” – The Guardian
