"Through performance we realise a deeper level of personal / collective catharsis which is the function & purpose each song, which is a vehicle for ritual / ceremonial drama and profound magickal transformation and potency."

Something akin to Aristotle's "Catharsis of the emotions of pity and fear"? From what I've read, the authentic re-enactment of early Greek theatre, in its traditionally masked form - *can* even now, be an intensely transformative experience for the 'viewer as ritual participant'.

Sing4Peace I've heard of Myss, but I recall reading Pinkola-Estes some years back and being most affected. One of her wee books touched me the most though "The Gift of Story" where she describes her families emigration from Hungary (?). Hard to recall now, but I remember the offering of watering tears to a young garden of trees as something deeply human, correcting, and instinctively soulful at the same time.
