Nein Nein by Tanzwut

What an awesome band, they deserve your total support. I certainly recommend this band, buy their album you will not be disapointed. Celtic Metal? that might describe it but what I think makes this band work is their heritage of communal singing, there is something contagious about Tanzwut.
