Following their Give Me Ed... 'Til I'm Dead Tour in the summer of 2003, Iron Maiden released "Dance of Death", their thirteenth studio album, which was met by worldwide critical and commercial success. Produced by Kevin Shirley, now the band's regular producer, many critics also felt that this release matched up to their earlier efforts, such as "Killers", "Piece of Mind" and "The Number of the Beast". As usual, historical, and literary references were present, with "Montségur" in particular being about the Cathar stronghold conquered in 1244, and "Paschendale" relating to the significant battle which took place during the First World War. During the following tour, the band's performance at Westfalenhalle, in Dortmund, Germany, was recorded and released in August 2005 as a live album and DVD, entitled "Death on the Road".
