Radiophonic Workshop In Concert stage

Quotes

I began by interpreting the actual letters, I.E.E. one hundred, in two different ways. The first one in a morse code version using the morse for I.E.E.100. This I found extremely dull, rhythmically, and so I decided to use the full stops in between the I and the two E's because full stop has a nice sound to it: it goes di-dah di-dah di-dah.

I wanted to have, as well as a rhythmic motive, to have musical motive running throughout the whole piece and so I interpreted the letters again into musical terms. 'I' becomes B, the 'E' remains and 100 I've used in the roman form of C."
   -- Delia, from recordings used in Sculptress of Sound

Delia's ability to take on enormous projects to order was [shown] when she composed a special extended electronic piece for the Institute of Electrical Engineers which was performed before the Queen and Prince Philip at the Royal Festival Hall. Taking the initial letters IEE, Delia composed music from their mathematical correspondences and from morse code: introducing elements of the development of electricity in communication from the earliest telephone to the Americans landing on the moon. There was the voice of Mr Gladstone congratulating Mr Edison on inventing the phonograph: the opening and closing down of Savoy Hill with Lord Reith's voice: and Neil Armstrong speaking as he stepped onto the surface of the moon. The powerful punch of Delia's rocket take-off threatened the very fabric of the Festival Hall.

“IEE 100,” [was] intended to show off the capabilities of the new Synthi 100. [...]
   In reality, the premiere of Derbyshire's work very nearly didn't happen. Typical of her method of working, she had developed numerous ideas and written detailed notes about the piece, but put off working these ideas out until the last minute. The night before the concert, as Derbyshire was still putting the finishing touches on the piece, concert director Hodgson started to get a bad feeling about her mood. He instructed Workshop engineer Richard Yeoman-Clark to secretly make two copies of the tape she was having him run of the final version of the work and to give Hodgson the second copy that night. He recalls: “I said to Richard, ‘Run another set in Room 12, don't tell Delia you're doing it, and that copy bring to me in the morning, because I have an awful feeling she was going to destroy the tape.’ And he did that. And she came in the next morning in tears, around 11 o'clock. And said, ‘I've destroyed the tape, what are we going to do?’ I don't think she ever forgave me for that.”
In some ways the seven-minute piece resembles much of Derbyshire's earlier works, particularly in the use of complex, drawn-out tape pedal points, in this case, layering on to of these excerpts of famous events in scientific and broadcasting history, such as the Apollo moon landing and the opening and closing of the BBC's Savoy Hill studios.
