Glassiness & Glamour

I've been greatly enjoying the recent discussions of 'that voice' over at blissblog and mit Emmy Hennings: that glassy, slightly patrician, un-grainy female voice that I at least find impossibly alluring: something surely added to by the 'Beat Goes On' video linked to, and by the Russ Meyer connection. Isn't part of what's quite so exciting about that voice the fact that it's sexy without being earthy, suggesting all manner of perversity without all the athletic emoting and grinding that it's more R&B competitor suggests...?
