In a new clip from Brett Morgen's upcoming Kurt Cobain documentary, Montage of Heck, an early, teenage Nirvana performance is unearthed and the band's bassist Krist Novoselic speaks on his early relationship with the frontman. You can check it out in the player below (via The New York Times).

The early performance appears to be in one of the rockers' living rooms, with the narrator saying, "If we played in the house for a couple of hours and if two people would stop by we'd consider that a gig, you know, a show. That was good enough. We had an audience of two people, locals who hated our guts and thought it was terrible music."

Speaking about Cobain during the interview portion of the clip, Novoselic says, "He'd always have to do some kind of art -- usually defacing something. He never had, like, idle hands. It just came out of him; he had to express himself." He also mentioned that Cobain was a janitor the first time they met.

In the Times article, Morgen made it clear that any sort of interview with drummer Dave Grohl will not be included as a DVD extra feature (we already knew that Grohl was supposedly left out of the feature). Montage of Heck is currently being screened in select theaters but will air officially on HBO on May 4.
