It is with mixed feelings and some surprise that I see this has finally come out on CD. Please keep this one a secret. It's far too delicate to survive being culturally hegemonized with some tedious driving dance beat. I have had the vinyl LP for years and have always jealously thanked the higher powers that charlatans with no sense of history did not use it to lend proxy 'quality' to modern electronic pop. I guess it's only a matter of time before this disc gets plundered for hooks - alas. This is 'collage music' from a time where you had to do it with razor blades. Analogue sampling from the 1960s and 1970s, manipulated tape, tone generators and all that. What's striking is how much SPACE there is in these sounds, a quality which comes from the short duration of most of the tracks (it's experimental library music financed by BBC license payers), and the complete absence of drum tracks. With some of these samples, twanging rulers, clinking milk bottles and the like, who needs 'real' percussion anyway? Musically, we hear childish rhymes, martian heat rays, backwards medieval chants ("his wish, faith to the master"), riffs, loops, clicks and beeps of all kinds. Some of the samples are recognisable from the 1969 White Noise album that Delia Derbyshire also worked on. If you dig that album, get this too. A splendid aural complement to the vogue for TV idents, test cards and 'Schools and Colleges' graphics. The John Craven's Newsround 'and finally' tag also makes an appearance. A must buy for all eclectic electronauts and sonic gourmets everywhere.
