One Person Sings Two Notes At The Same Time, Amazingly Freaky [VIDEO]

One woman, singing multiple notes at the same time, this may be one of the weirdest things you will ever hear.

Her name is Anna-Maria Hefele and she does something called polyphonic.  This is when one person sings two or more notes at once.  What you will hear has not been auto-tuned, touched up or altered.  It sounds like a really strange electronic instrument.
