Favorite Female vocals that give you goose bumps

Grace Potter, Alison Krauss, Maria Muldaur, Amy Lee,(lead singer Evanescence)and Bonnie Raitt, as well as most others mentioned.

Jane Relf - the lead singer for the original incarnation of the group Renaissance, and later the group Illusion (and sister of Kieth Relf). I've mentioned her her before though and get the impression I'm the only one who is so impressed by her.

Of those previously named - here are some I really, really like:
Eva Cassidy, Julie London,Amy Lee, Lisa Gerrard, Margo Timmins

If there is one song and performance that comes to mind that gives me goosebumps almost every time I hear it, it would have to be Kate Smith singing "God Bless America"

Tubegroover,thanks so much for that heartfelt sentiment(and for a very big bellylaugh).

TransNova: Linda Rondstadt is a George Massenburg recording-he is one of the best there is. He builds his own gear (I sell it to studios) and it defines "transparent" in pro audio world. Look up his other recordings-all of them fantastic. Like Dawn Langstroth (Anne Murray's daughter), he recorded a lot of live. Look her up on you tube to see George sitting in the middle of the track space mixing.
