Evil Sword is a bunch of nutballs. When I asked singer/flautist Kate Ferencz what brought her (and her spooky, lo-fi pop skills) to Philly, she told me a strange little story about her New York apartment being infested with giants who “ended up eating our other roommates. And after that we couldn’t pay the rent.” So now we have them, and they have a murky, messy, playful new cassette/download called Flesh Eating Mold Will Devour You coming out on Single Girl, Married Girl records and a release show/costume party to go along with it.

City Paper: What is Evil Sword’s deal?

Kate Ferencz: Now we just have the one giant thumping around in our basement, but we need to keep having band practice to cover up sounds he makes so our neighbors won’t notice anything funny and start to wonder where all of their stray cats and small children have gone. And in the process of doing that we try to make the most beautiful music that we possibly can.

CP: You guys love Halloween, eh?

KF: Halloween is the happiest time of the year, mostly because of all of the costumes, but the trick is to structure your life in such a way that you have reason to be making costumes all of the time.

CP: Is flesh-eating mold something I should be worried about?

KF: Yes.

CP: What else?

KF: Regardless of what time of year it is, if you come to an Evil Sword show you are expected to wear a costume.
