This book does not cover the entire career of Rudy Sarzo (who has played with Quiet Riot, Whitesnake, Dio, Blue Oyster Cult, Yngwie Malmsteen and many more), but focuses on his time in Ozzy Osbourne's band, and particularily on his friendship with guitar legend Randy Rhoads. The two played together in Quiet Riot in the early 70s, and then again in Ozzy's band, until Randy died in a plane crash in March 1982.
While this book is a fitting tribute to Randy, it certainly holds nothing back when it comes to describing the wild and crazy life on the road as Ozzy's career took off. All the tour antics are in here, in surprisingly good detail, as Rudy kept a diary. The level of detail does get a bit absurd at times, when entire conversations are recreated in dialogue form - at length! These usually end up feeling rather constructed, but are probably meant to give an indication on tone/how things were discussed, so you learn to accept them.
Overall, the book is a wonderful read, and gets more and more poignant as you get nearer that fateful day when the plane crashed. A book full of laughter and tears, just like any good book should be.
