Spank the Planks has the information on this group.  They are based in Bournemouth and specialise in Appalachian clog dancing which is a form of American folk dancing that originated in the Appalachian Mountains. The local people developed their own musical sound, playing mainly fiddles and banjos and complimenting the music with a percussive dancing style that used shuffles, taps and scuffs to keep time. 

Their dancing is exciting - very fast and very loud.
