So I asked Twitter for some awesome bands with female singers (apart from Arch Enemy), and this is what we came up with:-
Frosted Leaves "Depth" (Iran)
Crucified Barbara "Killer On His Knees" (Sweden)
Ishmael "Little Bones"
and my favorite,
iwrestledabearonce "You Know That Ain't Them Dogs' Real Voices" (US)
Always happy to hear more, keep the recommendations coming!!
