Love Lydia Lunch!

She's the queen of no wave. Her solo stuff is great as well, albeit in a somewhat different direction than TJ&TJ.

Tegan that sang with Against me in the Borne on the fm waves of a heart is cool

it all depends on the style that the girls are singing in, if you listen to The Donnas, The Breeders, L7, and listen to earlier styles of punk, what was actually considered funk punk back in the day, like The B-52's... they all do a great job, but not always in a yelling way.... women are just more naturally inclined to sing in a more melodic and harmonious fashion than men.. let's not be self-defeating or counter-productive, though.. in the end, it's all about whether or not the music is good, and if you're listening to it, it's probably good..

My favorite punk song.

Getting Nearer - Tribal Fish

I like:
Isis Queen from the Barb Wire Dolls
Kelly Ogden from the Dollyrots
Alice Bag
Wendy O. Williams
Theo Kogan from the Lunachicks

Jack off Jill has been said a number of times here which I side with as well a many other notable female punk singers. That the 30 pages of mostly female punk singer recommendations I would say has changed this thread from OP's original topic.

So instead I shall trawl through these reconsiderations for my own pleasure.

Corin Tucker for the win.
