Dave Grohl says his late Nirvana bandmate Kurt Cobain's personal problems have created a false image of the 90s group.

In an interview with The Scotsman, Grohl, who played drums in Nirvana, acknowledged the singer's troubles with addiction.

But he said the way they had been portrayed since Cobain's death in 1994 had influenced too much on the band's legacy.

"It's easy to imagine that we were followed by a black cloud. But it wasn't all misery and doom,” Grohl said.

“People know the biography, but it's a little more complicated than that."

Cobain committed suicide following an ongoing battle with addiction.

Meanwhile, Grohl, who went on to front the Foo Fighters after the singer's death, also spoke about his new side-project, Them Crooked Vultures.

He said the group, which also consists of Josh Homme and John Paul Jones, had felt natural from the beginning.

“Only a few minutes passed before it felt like not only a band but a really good one," Grohl said.

Them Crooked Vultures released them self-titled debut album earlier this month.
