Moyst Technical Explanation Number One

In order to enhance the "otherworldly" quality of Alpha's voice, she was recorded 180 degrees out of phase. This is the trick used to erase vocals from karaoke soundtracks. In this version, when the two channels are combined, Alpha's voice vanishes. In stereo and surround sound, however, the center channel vanishes, and Alpha can only be heard from the extreme left and right, which was the effect intended.

Thanks!
