Retrieval is not simply a matter of hauling the old thing back onto stage, holus-bolus. Some translation or metamorphosis is necessary to place it into relation to the new ground—as anyone can testify who has experienced “revivals” in our culture, whether in fashion or music or any other forms. The old thing is brought up to date, as it were. For archaic or tribal man, in acoustic space, there is no past, no history—always present. Today we experience a return to that outlook when technological breakthroughs have become so massive as to bring one environment into collision with another, from telephone to radio to TV to satellite to computer.
