TONY VISCONTI: "I had to rig up a special microphone technique which cancelled the band but recorded his voice. This required two identical microphones placed electronically out of phase. In other words, the diaphragm of one mike is pushing when the other is pulling. The band's sound is picked up by the two mikes, but is out of phase and consequently cancelled! David was told to sing only into the top mike so that his voice was not cancelled! For the non-technically-minded this probably doesn't make any sense, but it saved the day, and what you hear on the recordings is about 85% 'live' David Bowie".
