Iron Maiden has released over a dozen live records, so the first question for any practical fan is, "do I really need another one?" The Book of Souls Tour is perhaps the most significant in the band's history because it was the first singer Bruce Dickinson undertook after completing treatment for throat cancer. Not only did he sing, but, as usual, piloted the band's 747 to 39 countries on six continents in 2016 and 2017. The band performed in front of more than two million people. The set was produced by Tony Newton with assistance from bassist Steve Harris.
