This book is pretty good. It's accurate for the most part. There are a couple mistakes I spotted,but it's nothing major. It's a fast read so if you're a Nirvana fan on the go,this book is for you. To give you an idea of how fast you can read this,while still absorbing the information,I was able to listen to all of In Utero with the bonus track. That's about an hour, I believe. The pictures in this book are fantastic. All in all this book is worth your money.
