The concert was notable for being the first time a western rock band had played in Cuba. Fidel Castro was in attendance, and met the band before the concert. The film's title came from a conversation between the band and Castro; after the band warned him that the concert would be very loud, Castro responded (through his translator), "It cannot be louder than war, can it?"
The concert was also notable for featuring performances of several songs from the band's then-current album Know Your Enemy, some of which have not been performed since.
The bonus live tracks are taken from the same concert - out of sequence - and are presented in lower sound and video quality.
