Ah, “Fack”: Eminem’s strangest song (and he has some strange ones!) lives on in Slim Shady lore as the Curtain Call: The Hits cut to feature Em ejaculating multiple times and shoving a gerbil tube up his butt. Before now, the world has been spared a proper performance of “Fack”… but that all changed this weekend.

To close out his headlining set at Lollapalooza Brazil on Saturday night (Mar. 12), Eminem ceremoniously broke out the 2005 track live for the first time. His manager and Shady Records co-founder Paul Rosenberg helped capture the madness on Instagram:

Eminem’s got Lollapalooza performances in Argentina and Chile scheduled for this weekend. And hey, did you hear that The Slim Shady LP got a cassette reissue?
