Charles Cross's popular biography of Kurt Cobain is alarming reading. I read Michael Azzerad's Come As You Are back in '94 and remember an acutely different tale. Azzerad was fortunate enough to have had extensive interviews with Cobain, unlike Cross, and his book is strikingly disimilar to this.
Ultimately, I think Cross's account is the more accurate of the two. It is also somewhat different in tone, being a biography of Kurt Cobain, not Nirvana. Cross pulls no punches, and his book is the better for it.
Cobain's duplicity as recorded here is astonishing. This is a compelling account of a man who desparately sought fame and recognition, who invented a history for himself barely worse than his actual past and, inevitably, this is a story of serious drug abuse.
The second half of the book - detailing the years 1991 to 1994 - is overwhelmingly concerned with Cobain's addiction to heroin. Contrary to popular belief, the singer was rarely clean for more than a few weeks during the last three years of his life. This is not light reading; it is the painful account of a young man's weakness and mental decay.
Throughout the book, Courtney Love is respectfully portrayed by Cross as a loving wife and supporter of Cobain. No doubt this is true in some respects, but you get the impression Cross backed-off detailing much of Love's character. In return she provided him with access to Kurt's diaries, some entries from which are published here. It was a reasonable trade-off, I suppose, but not terrific journalism.
Interesting and often horrific, Heavier Than Heaven is a valuable biography for its honesty, and the only essential piece of writing on Cobain so far. Recommended.
