Bshapperd,
I have a few of their other CDs, I forget the names but they were recommended by All Music Guide as their best and they do not have the flavor of Is A Woman. They are distinctly more alternative sounding (which is usually fine with me) and I find myself not listening to them as much as Is A Woman.
Another good group is called: Ida.
Their CD called Will You Find Me? is a very nice mix of vocals harmonizing with acoustic guitar and organs and an eclectic mix of wind instruments. This album is very tastful and again, like Lambchop, I prefer this to the others that All Music Guide rates as their better albums.
