Query: Barlowgirl's definitely don't keep silent!

BarlowGirl's are one of those artists for me that I have followed since the beginning of their career. I love How Can We Be Silent because it is full of so much maturity and growth. BarlowGirl has finally established themselves as a top rock band in Christian music. How Can We Be Silent is full of amazing melodies and even stronger lyrics. Its a little cliche but I can't think of a better band for preteen and teen girls to be listening to. Though this album should easily appeal to any rock fan!
