The first couple of chapters were interesting, explaining the links between slaves bringing over drums from Africa and how drummers were often considered the bottom rung of any band. But, the author needed more focus as he continued throughout time. There seemed to be a lot of repetition of themes. He would circle back to Ringo Starr or Gene Krupa again and again. And similar to one of my biggest pet peeves -- the useless word "literally," Brennan was stuck on the word "indeed" to begin far too many sentences. Since I was listening to this on Audible, I would hear the word and cringe. Overall, an average book. But, hey, it's about drums, and that's a good thing. :)
