Machine Gun Kelly disses Slipknot as “old weird dudes with masks” during Riot Fest set

Machine Gun Kelly‘s Riot Fest set has indeed started a riot, though probably not in the way he intended.

The “Bloody Valentine” rocker took a moment during his performance at the Chicago festival to share his thoughts on Slipknot, who were playing at the same time as him on a different stage.

“Hey, you wanna know what I’m really happy that I’m not doing?” Kelly asks the crowd in fan-shot footage posted to Twitter. “Being 50 years old, wearing a f***ing weird mask on a f***ing stage.”

During another point in the show, Kelly said, “Turn the lights up. Let me see who chose to be here instead of with all the old weird dudes with masks,” according to the Chicago Sun-Times.

Metal fans on Twitter naturally came to the Knot’s defense, often referencing how Kelly seemingly switched from rap to rock after getting into a feud with Eminem.

“He started unnecessary aggro with Eminem and had to change genres,” tweeted one commenter. “I look forward to his new jazz album after Corey [Taylor] destroys him.”

As for what inspired MGK’s Slipknot diss in the first place, it might be response to Taylor’s comments earlier this year in which he said he doesn’t like “artists who failed in one genre and decided to go rock.”

While Taylor didn’t mention Kelly by name, he did add, “I think he knows who he is.”
