Polish female fronted Traditional Heavy Metal act Crystal Viper, released the "one take no dubs" video to the song "Night Of The Sin". The song is taken from the last Crystal Viper studio album Legends - and this is a rare chance to hear it in its "live version", as the song was recorded without overdubs, and the recording was not mixed and mastered.
I like this \m/. There are a lot of female fronted bands not in the goth genre. For example "Sister Sin": (http://www.youtube.com/watch?v=y3rfFX0ilTg), although they are more a Hard Rock band, I think. In Heavy Metal, I can mentionate "Widow", in the album "On Fire" (http://www.youtube.com/watch?v=xObNdGLcvN0). And in other genres there are of course more known bands, such as "Arch Enemy" or "The Agonist".
