The Moravian Church has an amazing musical tradition. You should make a point of visiting Old Salem (Winston-Salem, NC) or the nearby historic communities. If I recall correctly, the Moravian settlers arrived by the same routes as their Scots-descended neighbors.

The Easter sunrise service of the Home Moravian Church. involves a band of about 400 pieces.

Salem was the southern center of the Moravian settlements, as Bethlehem, PA was the northern center. I'm sure they have equally amazing things in the Lehigh Valley of Pennsylvania, but I've never been there.
