Okay, after hearing something here about the Four Bitchin' Babes, I broke down and bought one of their CD's, viz., Gabby Road.

Love it!

Thanks everyone who suggested 'em.

Their harmony sounds a little like Uncle Bonsai, or like the Roches on Hammond Song. Is that just because it's 3+ part female harmony, or is there some "style" that they share?
