Este som que nos enlouquece... A culpa é do microfone.

Horn (6:21), de Gordon Mumma

Gordon Mumma, French Horn; Robert Ashley, Cybersonic Console; George Cacioppo, Cybersonic Console.

Horn is a live-performance electronic "chance" composition. The sound source is a French Horn fitted with a special mute containing a microphone. The sounds from the microphone are fed to the two cybersonic consoles (transistorized sound modifiers). The consoles are operated by two performers who determine the continuity of the work during each performance, according to the conditions specified by the composer. Thus, the composition changes at each performance.
