The band Biella Nuei plays traditional music of Aragon (North of Spain) - one focus of their music is the Aragon bagpipe, another surely the traditional song. Their music brings back the music from the ancient times. Biella Nuei is doing a great job in helping this regional music to survive. They play instruments such as "gaita de boto" (pipes), "chicotén" (psaltery) and "dulzaina" (double reed instrument in the oboe family). http://es.wikipedia.org/wiki/Biella_Nuei
