So this book is the older transcription of the two big Rush tab books, the newer one being the deluxe collection (verses the anthology). Certain songs are played a little differently. Most notably legato section of YYZ and the chordal structure in Tom Sawyer. The tabs ARE CORRECT. I have the Rush Replay x3 and these tabs are how Alex played them back then, but those are older dvds. In R30 and Time Machine especially you can see how he changed it up. However, I have enjoyed this book because it is correct, it has tons of songs, and I'm a HUGE rush fan. If you can keep up with Lifeston and you like Rush this book is awesome. The only better thing is the deluxe guitar tab collection which tends to run a little more.
