Cut ups, mash-ups, circuit bending, tape-mangling and, oh yeah, the Dr. Who theme.
One of the true innovators of electronic music. And yes, she’s the person who “realised” (arranged, performed) the Doctor Who theme.
From wikipedia: “In August 1962 she assisted composer Luciano Berio at a two-week summer school at Dartington Hall, for which she borrowed several dozen items of equipment from the BBC. One of her first works, and the most widely known, was her 1963 electronic realization of a score by Ron Grainer for the theme tune of the Doctor Who series, one of the first television themes to be created and produced by entirely electronic means.”

Still the best theme in regards to how it was made, how it’s one of the first pieces of electronic music ever, and how it’s (basically) the same theme still, 50 years later.
