The tour, following the album, dubbed the World Slavery Tour, was the band's largest to date, and consisted of 193 shows in 28 countries over 13 months, playing to an estimated 3,500,000 people. Many shows were played back-to-back in the same city, such as in Long Beach, California, where the band played four consecutive concerts. Their first live album, "Live After Death", was recorded, which became a critical and commercial success, peaking at No. 4 in the UK. Iron Maiden also made their debut appearance in South America, where they co-headlined (with Queen) the Rock in Rio festival to an estimated 300,000 in attendance. The tour was physically gruelling for the band, who demanded six months off when it ended (although this was later reduced to four months). This was the first substantial break in the group's history, including the cancellation of a proposed supporting tour for the new live album, with Bruce Dickinson threatening to quit unless the tour ended.
