My son mentioned something about esctatic dance the other day.  I've never heard of it!
It is a free form type of dance event that is based on Gabrielle Roth's "5Rhythms" guided dance practice.
Ok, I'm still clueless.  Who is Gabrielle Roth?
She was an American dancer and musician in the world music and trance genres. She also had a special interest in shamanism.
