The Roy Hart Theatre in France is known for its voice research and its unique methods of teaching singing. Producer Eva Odrischinsky attended workshops there for ten years and worked closely with its best singing teachers. Taking a cheap little tape recorder along to remind herself of what went on and how it sounded, she accumulated a large sound diary. This work is an unusual document showing how exciting it can be to experiment with the human voice. The Voice is the Muscle of the Soul won the 1989 Ake Blomstroem Award (Swedish Radio) for the best European-style feature by a new and promising producer. An English version remixed especially for the series, presented by New American Radio.
