If you haven’t been following AV Club’s Holiday Undercover series, which has found the likes of Wye Oak and Little Scream covering both classic carols and Christmas-appropriate tracks by everyone from the Velvet Underground to Low, you’re missing out on a vital bit of seasonal cheer. But the high point of the set is its final installment — a close-up video of the Mountain Goats (that is, John Darnielle) performing “Have Yourself a Merry Little Christmas.” While Darnielle plays it straight, sweet, and typically intense for most of the song, fans can rest assured that he throws a respectable black metal aside in at the 2:51 mark.
