Xera is an Asturian electronic folk music group. Their sound is an integration of electronic and traditional Asturian music, mixing live instruments with samplers, industrial percussion... with a symphonic treatment that result in a very wide spectrum of sensations. They have published their first full work, "Lliendes" (Legends, in Asturian language), under a Creative Commons License (by-nc-nd).
You can buy the CD or listen to the full album for free in their webpage: http://xera.com.es where you can also find more info about them (philosophy, concerts, etc.).
