Today's theme from Saturday is from 1969 and from Delia Derbyshire, the woman at the heart of the BBC Radiophonic Workshop. Delia's Theme is a little under one and a half minutes of Delia, a vintage synth and some oscillators. It was originally released on an album called Standard Music Library, sound effects and short pieces of music for radio and tv. If you ever see a copy in a charity shop, snap it up for me please.
Delia is much better known for this theme, a groundbreaking piece of tv music, built round that famous two note bassline with tons of reverb and some whooshing siren noises. Despite being very well known and instantly recognisable it's still a startling piece of music.
