Contrary to their quirky wit, Kate and Anna also tackle serious stuff. A solo piano or acoustic guitar introduction is a clear sign that they're about to "reach for the heart." `I Cried For Us' is a simply structured but sorrowful "good-bye" composition. There's a heartwarming song about independence and apprehension which manages to sound 100-years old (On My Way To Town). Loss and fear are the subject of the touching `Babies If I Didn't Have You.' Love Over And Over celebrates life's pleasures and tribulations. Very gratifying.
