But Dave Grohl is a rock star today in his own right and Krist Novoselic can still kill it on bass and there are tons of musicians out there who would kill to play with them.
So on Jan. 4 they did just that, teaming with Beck, St. Vincent, and even Grohl's teen daughter Violet for a set at the Los Angeles Art of Elysium Gala, which Rolling Stone reports is "an annual fundraiser that connects artists with children and communities in need."
The supergroup played for famous audience members including Bella Hadid, covering hits like "Heart-Shaped Box," sung by Violet Grohl, and "Lithium," which was performed by St. Vincent.
They finished the set covering “The Man Who Sold the World," a David Bowie classic which Kurt Cobain made his own in the epic MTV Unplugged in New York.
