We remember when the prayer chants of the Guyoto Monks were first released in 1986. Micky Hart, one of the drummers of the Grateful Dead, was the producer and the weight of his name was enough to make us sit up and listen. Then the chanting itself captured our undivided attentions. It was the first time many of us had heard overtone singing, which is to say when a person is able to sing a primary note and the harmonic overtone at the same time. It was an illuminating experience! Please note, that the chanting on this recording is not performance, for the prayers are said anew each time the recording is played. Their power and effectiveness depends, of course, on the degree of attention and compassion which one brings to bear on the experience. The positive effects can therefore vary from merely an illuminating understanding of a vocal technique right on up to a moment of spiritual enlightenment.
