If nothing else, Two Nice Girls have provided us with the ultimate (and, it is hoped, final) variant of George Bush's ''kinder, gentler nation'' line: ''Is this my good fortune?/I'm finally in luck,'' sings Gretchen Phillips. ''Now what I receive is a kinder and gentler f---.'' The Girls there are actually four of them, and part of the point is that they're not always nice sing songs about feminism and lesbianism, most of them sensitive enough not to be alienating if you're not already a convert. The girls are basically folkies, but are willing and able to rock out. Chloe Liked Olivia is pristinely produced and occasionally startling: ''Throw It All Away,'' by bassist Meg Hentges, has a lovely chorus and is sung by her in a rich, burnished voice. But not everything gels. Despite the rock & roll and more bawdiness (''The Queer Song,'' a lusty rewrite of Buddy Holly's ''Not Fade Away''), there are long spots of lethargy. But occasionally the foursome gets into a jazzy laid-back groove; it turns out that besides polemics and humor, Two Nice Girls can display some soul as well. B-
