God's Cricket Chorus

From YouTube:
Experimental director, composer and playwright Jim Wilson recorded the sound of crickets and then slowed down the recording, revealing something so amazing. The crickets sound like they are singing the most angelic chorus in perfect harmony. Though it sounds like human voices, everything you hear is the crickets themselves. There are two tracks, one is played at regular speed and the other is the slowed version. The singing you hear are the crickets only. No instruments or voices were added.
