Sometimes the Cat

What in God's name is Sometimes the Cat? Sometimes the Cat is music for your ears. Also, the rest of you. And your mind. But not your heart, because that's for blood. And not your soul, because souls aren't real, nitwit. Okay, that was unhelpful as shit. Who in God's name is Sometimes the Cat, then? Sometimes the Cat is usually played by this kid named April Friedman who comes from the mythical land of Oregon, but we don't know if that's who actually makes the music. There's no way one person can do all that stuff.
