Stuart Dempster in his The Modern Trombone wrote about the use of electronics: “A tape often is really only a substitute for something that might sound better accomplished by another method; this other method might, however, be prohibitively costly or problematical. Usually the audience is served up this sort of acoustical compromise, or a synthetic diet of pure electronics which can be even worse.”
He gives a few exceptions to this comment: David Behrman, Gordon Mumma, and David Tudor.
His other main complaint about the use of electronics sound is, it is “too perfect”: “I firmly believe that is it the little imperfections that make musical sound, or sound in general, so interesting.” He comments on how Pauline Oliveros often seeks out and incorporates the imperfections in electronic sounds in her music.
