Inception star Joseph Gordon-Levitt took the stage on Tuesday night and gave fans a treat with an impromptu cover of Nirvana’s hit Lithium.

“You know it seems like every time people bring up Nirvana, people want to talk about how Mr. Cobain killed himself,” Joseph said to the screaming crowd.

“I gotta say, it doesn’t matter to me. It doesn’t matter that he’s dead, it doesn’t matter how he died, his songs are f***ing awesome, that’s what matters!”
