The Barra MacNeils
Celtic traditions. They come from Cape Breton Island, where there are still a couple of thousand Gaelic speakers and lots of traditional music, and their name refers, a bit humorously, to the Hebridean island of Barra, an ancestral home of Clan MacNeil. You might expect the Barra MacNeils to fall at the traditional end of the spectrum. They do play "sets" medleys of traditional dance tunes, and they learned step dancing from their mom.
