In this song from Portland's Times Infinity, the singer is pleading with Krampus to take his/her sister instead. She's the bad seed after all. And, "next year, with your hooks and your claws, perhaps you'll take an interest in Ma and Pa." It's slyly funny like that throughout. By the way, the big day for Krampus is December 5th. So, if you're reading this, you should be safe for another year.
"Krampus Baby" purports to be from Volume 2 of "A Festive Odyssey" but, as yet, its the only song listed. However, that shouldn't stop you from picking up Volume One, which is also free at Bandcamp.
