Mystery Celtic Metal band?

A few years ago, a friend showed me a Celtic Metal band on Youtube, and I've been trying to find it again ever since. I seem to recall the band was fronted by a woman who resembled Frances Cobain, and the video had a greyish atmosphere. The song sounded a little like Inis Mona by Eluveitie, but I don't believe it was, although it may have been a different song from Eluveitie. If anyone could help me out, that would be splendid!
