Saw a post recently describing the "hairs up on back of neck" reaction to music. I might describe it more as chills up and down my spine, but whatever it is, I got it when listening to Alison Kraus and First BAptist Church Choir. And that was in my noisy Jeep doing 75 mph!! I must admit to being a huge fan of hers since hearing her sing in a small venue in CT when she was still a teen. She did an a capella number that night with Union Station that just blew me away. Anyways, I'm not a religous guy at all but the harmonies, simple arrangements, and emotion in this kind of music strikes a chord in me.
Kelly, if you can recommend some other stuff like this, I'd be grateful. I have Cox Family/Allison Kraus CD and lots of other bluegrass/folk/roots stuff, but always looking for more in this vein.
