If you enjoy these types of haunting Celtic melodies, two CDs I'd recommend trying to find are Bach Meets Cape Breton on the Marquis Classics series, and the sound track from The Last of the Mohicans. The Cape Breton group plays harpsichords and strings and does these great, folksy renditions of Bach (and you have to listen closely and know what to listen for to hear the Bach). It's one of my favorite pieces to listen to when backpacking. At the end of a long, tiring day, I'll suddenly be doing jigs and gavottes down the trail with 50+ pounds on my back! I've gotten many a strange look on the trail while "dancing" in my own world, (OK, so I get lots of strange looks all the time, but that's another topic!). The sound track from Mohicans keeps coming back to a French/Breton jig theme played simply on a fiddle that is also perfect for the wilderness or paddling a canoe. Both of these put me into the minds of early French trappers, being the first of their race to see some stretch of uncharted wilderness. Great feeling, if only a fantasy.
