Nirvana's former manager Danny Goldberg has revealed in a new book the impact that Courtney Love had over her late husband, and the band's frontman, Kurt Cobain.

Goldberg, who also worked with Led Zeppelin, claims that Love acted as Cobain's “mouthpiece”. He also details the extent of the pair's alleged problems with drug addiction.

"Courtney's very presence was a metaphor for the end of one era in the band's life and the beginning of another," he writes.

In the book, Bumping Into Geniuses: My Life Inside The Rock And Roll Business, Goldberg details one particular incident before the band's appearance on Saturday Night Live in 1992.

He claims that Love asked him to get the couple $5,000 in cash so that they could go “shopping”.

"I felt pretty uncomfortable as I delivered the package of $100 bills to her [Love] at the hotel,” he writes.

"Abruptly, the dark cloud of drug excess had entered the band's life. I was confronted by the baroque facade of lies and the awful glassy-eyed deadness that regular heroin use provides."
