Maybe I am chauvinistic but I just can't get into Girl metal. It just doesn't go. I don't care much for girls shredding on guitar either. But there are voices that I love like; Ann Wilson, Pat Benatar, Patty Smyth, Whitney, Tina Turner, etc.
I don't care much for female drag racers too but I did date one and my wife reminds me of it.
The only female fronted bands I like are Nightwish and Within Temptation. I don't see anything wrong with girl metal. Girls shredding on guitars on youtube are for young and old men who don't get laid though. Different with someone like Nita Strauss who is really talented. So how long time did it take you to realise it was a man?
I had a friend and his big brothers friend when he was really drunked deep kissed one on the dance floor. They tried to warn him but he refused to listen and found out with the pants down.
