My wife and I actually saw Eluveitie back in February. They were one of the opening bands when we saw Children Of Bodom in Cleveland. I don't mind folk metal, but they had too much going on at once, especially for a live setting and it just sounded awful. A horrible, jumbled mess. Not to mention the singer insisted that the crown get far too rowdy and a lot of people ended up leaving the show covered in blood. NOT fun at all!
I will say that Europe has the best metal, especially Sweden and Finland! Alaska has some pretty decent metal bands as well. Some bands that I can't get enough of are Opeth (earlier), Soulfallen, Turbid North and Daylight Dies.
