Katastrophy Wife: Heart On (2007)Paid $18.13This is a single from Kat's new album "Pregnant" that will be out soon, hopefully. There are 3 versions of "Heart On" and a Kat-style version of Iron Maiden's "Run to the Hills." Kat does not hold back when she sings/screams and no matter how old she gets her voice just gets more powerful. This is kind of pricey for a single, but you won't be disappointed. She's an amazing musician and I can't wait to hear the new album!
