A good starting place would be:http://www.io.com/~entropy/contradance/dance-home.html
(I never did catch on to those blue, click-me things, but you can cut and paste these URLs!)
This site has some samples of contradance music:

This is the homepage of Swallowtail, a favorite contradance band:

And Wild Asparagus, another hot band (with sound clips available on their homepage):

When I lived in the Phila. area I used to contradance every week. Since moving to the middle of cultural nowhere, I have really missed giving a balance and a swing in a big way! Again, sorry for the inconvenience of no hyperlinks.
