Cool! He got to work with a legend in writing his first book. Congratulations to Brian!
Now Brian, let's see if that 2nd book can't be the often mentioned possibility of a complete, definitive technological breakdown and exploration of the Brian May sound, from the making of his guitar, through the rigging of his amps, through a comprehensive look at his array of sound effects, including a deep focus into the Deacy Amp and it's creation.
I heard Greg Fryer will collaborate with him on a book that covers at least some of the above. I think he should go all out, maybe even recruiting some level of contribution(if possible) from John Deacon about the creation of the Deacy Amp.
Still, I am curious to read Bang!
