Much of the Unforgettable Fire Tour moved into indoor arenas as U2 began to win their long battle to build their audience. The complex textures of the new studio-recorded tracks, such as "The Unforgettable Fire" and "Bad", posed a challenge in translating to live performances. One solution was programming music sequencers, which the band had previously been reluctant to use but now incorporate into the majority of their performances. Songs on the album had been criticised as being "unfinished", "fuzzy", and "unfocused", but were better received by critics when played on stage. "Rolling Stone", which was critical of the album version of "Bad", described its live performance as a "show stopper".
