Harmoni mentioned the "goosebump effect"...yeah. That's what good harmony does...In my opinion, great music is identified by its affect on the autonomic nervous system.

I agree with all of the choices mentioned that I've heard, and I now have a list of new voices to listen to.

One "blood harmony" that deserves a mention are the Thompson twins, Chris and Meredith (no not that rock trio from the 80s!). They produce goosebumps...If you get a chance, check out "wood and stone"
