Wait, what? Did Christmas come early? Unreleased El-P material doesn't just fall into my lap every day. But it has, and it's my distinct pleasure to share it with you. Originally planned for inclusion on El's instrumental opus Weareallgoingtoburninhellmegamixxx3, "Lab Rat" initially didn't make the album due to a corrupted file. But it has since been salvaged, and is free to roam the internet in all its gritty glory.
