My brother is looking for an special effects or experimental LP he heard in college years ago which consisted of a voice recorded in a acoustic chamber. The voice was saying some well enunciated sentence. Then that tape recording was played in the same chamber and re-recorded. Then THAT tape was played in the chamber and re-recorded. and so-on. Then all the recordings are strung together so what you hear is a gradually deteriorating voice recording repeated over and over again until it is unrecognizable and starts to sound like electronic music or something. Has anyone heard this record and can you id it?? I'd like to try to find it for him.
