Avant Garde Project 59: Morton Subotnick II

AGP59 features three of Morton Subotnick's works for instruments and ghost electronics, supplementing those included in AGP6. The "ghost" electronics make no sound on their own, but alter the amplitude, frequency, and location of any sounds produced as the electronic score is playing. In his works for this technology, Subotnick explored the effects of these manipulations on a variety of instrumental combinations, from single instruments to chamber ensembles. The rather simple electronic manipulations in the "ghost" electronics nevertheless produce an interesting range of timbres, depending on the tone color of the instruments being manipulated.
