Even knowing all the sounds originated as your voice, GuitarBizarre, it was hard to believe the keyboard sounds (the melodic background notes) weren't really from a keyboard!
One reason is that they sounded so much higher than your speaking voice (the one saying things such as, "One day your life will flash before your eyes. Make sure it is worth watching). The overall effect of the piece is definitely interesting. It makes me think people could easily dispense with all other instruments besides the human voice.
Now you can call yourself "VoiceBizarre" and not just "GuitarBizarre."
