Loads of killer bands/releases mentined here. SACRILEGE's "Within The Prophecy" could be the heaviest Thrash album ever made. Fucking mindmelting stuff! ZNÖWHITE rips, MASQUE were incredible (one of my biggest wants!), KIM SIXX = awesome ('Power Baby' R.I.P.
), SENTINEL BEAST and BLACK KNIGHT were both way above average US Metal...
ACID is probably my fave female fronted Metal band. I can see if some find their more midpaced, classic Metal material to be mid-league stuff, but when they sped up they were one of the finest Power Metal acts ever, not to mention one of the earliest and most groundbreaking.
A very close second would be VIXEN (Hawaii). Criminally underrated early US Metal! Same goes for the MALISHA LP.
As for all-girl bands, my fave recording would be the MALIBU BARBI ep. Those songs are simply PERFECT Speed Metal! I would say ORIGINAL SIN, but they were apparently not a real band, so we'll have to put them in the 'fem-fronted' cathegory. Still, "Conjuration Of The Watcher" is just... INCREDIBLE!
DERKETA were more of a curiosity than anything really special in my ears.
LORETTA aren't good, they're awesome.
LORETTA aren't awesome, they're good. DUBL'1 (pre-MARKISA(RUS)) were awesome!
