Never forget: Metallica recorded a whole album with Lou Reed. Even if you don’t like the way that album turned out — and almost nobody liked the way that album turned out — you can’t doubt Metallica’s sincerity when they pay tribute to rock’s pioneers. And last night, they did it again, after a fashion. Metallica headlined the last night of a three-night stand at the Mexico City baseball stadium Foro Sol. And as an opening act, they brought along Iggy Pop. As their encore began, Pitchfork reports that Metallica invited Pop to the stage to help out on their cover of the Stooges’ proto-punk classic “TV Eye.” Watch a fan-made video below.

So, to recap: Metallica got a whole Mexican baseball stadium to chant along with an ancient nihilistic gargle of a Stooges classic. That’s a pretty cool thing.
