When I was in my teens, way back in the early fourteenth century, I had a copy of this record:
Konstantin Raudive. Breakthrough. Side A.
I can’t remember where I got hold of it anymore. In those days I was not quite as skeptical as I am today, and the notion of EVP excited me. So I promptly started doing my own experiments, using a simple tape recorder.
I never recorded so much as a peep from the Great Beyond, which is perhaps one reason why I became more skeptical about such things. If the experiment/observation cannot be repeated, it is problematic.
Anyway, listening to it again now, I surfed a wave of pleasant nostalgia. YouTube is truly a priceless resource.
