Frances Bean Cobain has spoken publicly about her father Kurt Cobain for the very first time. And while she says she's not that into Nirvana, she is a lot like her dad. In a Rolling Stone interview to promote the upcoming documentary, Kurt Cobain: Montage of Heck, she said, laughing: "I don't really like Nirvana that much. Sorry, promotional people, Universal. I'm more into Mercury Rev, Oasis, Brian Jonestown Massacre. The grunge scene is not what I'm interested in."

Cobain said that she did enjoy listening to "Territorial Pissings" on Nevermind and "Dumb" on In Utero, but stressed that her dad was no hero – a point that she was keen to come across in the documentary by Brett Morgen. 

"It's emotional journalism," she said. "It's the closest thing to having Kurt tell his own story in his own words – by his own aesthetic, his own perception of the world. It paints a portrait of a man attempting to cope with being a human."

She added: "When Brett and I first met, I was very specific about what I wanted to see, how I wanted Kurt to be represented," she said. "I told him, ‘I don’t want the mythology of Kurt or the romanticism.' Even though Kurt died in the most horrific way possible, there is this mythology and romanticism that surrounds him, because he's 27 forever."

Cobain is the executive producer on Montage of Heck, which uses home movies, gig footage, interviews, recordings and extracts from her father's journals and scrapbooks. She says that the film is an honest portrayal of a man who "didn't want to be the... voice of a generation".

"For me, the film provided a lot more factual information about my father – not just tall tales that were misconstrued, misremembered, rehashed, retold 10 different ways," she said. "It was factual evidence of who my father was as a child, as a teenager, as a man, as a husband, as an artist. It explored every single aspect of who he was as a human being."

Though Cobain prefers Oasis to Nirvana (there's probably a very delighted Gallagher brother out there right now), she did admit that she and her father are a lot alike – even giving her dad's former bandmates what they called the "KC Jeebies" when they hung out together.

"It's very weird how genes are," she said. "Dave [Grohl], Krist [Novoselic] and Pat [Smear] came over to a house where I was living... They look at me, and you can see they're looking at a ghost. They were all getting the K. C. Jeebies hardcore. Dave said, 'She is so much like Kurt.' They were all talking amongst themselves, rehashing old stories I'd heard a million times. I was sitting in a chair, chain-smoking, looking down like this [affects total boredom]. And they went, 'You are doing exactly what your father would have done."
