The Janes take a collection of songs that Thirty-Something Girls Like-"I Can't Make You Love Me," "Woodstock" and "Like A Prayer" are just several, but they're all good-begin with carefully constructed arrangements and pour their seven voices in a thick layer over the top. Sometimes "all-girl" groups can lack ballast on the bottom end, but Calamity Jane-as their name implies-gets the job done, relying on a foundation of dense block chords and ground bass figures. These gals aren't striving for a delicate, girly sound, but demonstrate that they can more than hold their own in the male-dominated world of contemporary a cappella.
