True haha the only band that all members are female I can remember Is Nervosa and Boy, these girls represent! Hard to say why...me and a friend was learning instruments (I was trying drums and she was trying guitar) but we ended giving up so soon because at least for me it was Pretty hard, I think men in overall is more interested not in metal but in learning guitar, etc. Nowdays I only organize these events for them to play but it's not happening for now because of this damn virus, But I had tons of fun practicing with the band.
