In an upcoming Biography titled This Is A Call: The Life and Times of Dave Grohl, it has been revealed that Dave Grohl quit Nirvana in 1993. While on a flight together, Dave overheard Kurt criticise his drumming stating in the book:
Kurt was kinda f—ed up. And I heard him talking about how s—-y a drummer I was.
At the end of the flight, Novoselic told Grohl that Cobain wanted him to “play more like” Mudhoney drummer Dan Peters, who had played drums before him. After hearing that, Grohl decided he had had enough and called tour manager Alex McLeod saying he wanted “out” of the band.
Apparently MacLeod told Grohl to calm down and convinced him to carry on with the band in a professional manner and he doubts that Cobain ever heard about the incident.
The book explains that by 1993 the band had almost split into two separate camps: Cobain and wife Courtney Love on one side and Grohl and bassist Krist Novoselic on the other.
