Google has recently scanned many great books. One of them is the essay collection Music and Technoculture, published by Wesleyan University Press in 2003. Here is an essay by Timothy D. Taylor entitled A Riddle Wrapped in a Myster, Transnational Music Sampling and Enigma’s Return To Innocence. The essay tells the story about how Michael Cretu sampled from a CD called Polyphonies vocals des aborigebes de Taiwan, and created the song we know as Return to Innocence. It also gives a fascinating description of the controversy that followed.
