dancing in the streets

I am reading this book called Dancing in the Streets by Barbara Ehrenreich.  Basically, of the part I've read so far, which is about a fifth of the book, the premise is that group rituals surrounding ecstasy or the creation of ecstasy are shaped by the experience of collective hunting.  This is framed in a very literal way.  But it got me thinking about group ecstatic rituals in the modern world and their relationship, and I arrived at the semi-stable idea that perhaps they are rituals of searching rather than hunting.  There's less urgency to survival now.
