Disregarding the novelty of hearing a six-year-old girl and her dad singing grindcore, I really enjoy both of these new songs by Sockweb. The girl can bellow and the music kills. I'd happily play this as anyone's introduction to grindcore. Check out "I Want Pancakes" and "Broken Glass Swan Dive" below.
