Yesterday marked 20 years since the death of Kurt Cobain. Last night St. Vincent paid tribute to the Nirvana leader during her show at Chicago’s Riviera with a cover of “Lithium.” Watch fan-captured video below.

Thanks Rey for the tip.

Coincidentally, Muse also performed the song last night, during their Lollapalooza Brasil set. You can watch that below.
