Paul Dutton, practitioner of soundsinging (song sounds), works on the possibilities of human vocal expression. He uses his voice as well as his glottis, his tongue, his lips and his nose as the main instruments of audio expression. Mouth Pieces gathers together, within the extreme limit of the technical and expressive possibilities of the vocal device, old and new works, combining poetry and music, the verbal and the non-verbal, the formal and the improvised. Without the effect of electronic processing, feedback, doubling or fading, Mouth Pieces presents, with remarkable accuracy, the audio essence of oral art by Paul Dutton.
