had the same vibe and it was exactly as it had been in 1983, nothing had changed! Even down to the broken shutter in the corner ... same carpet ... everything ... It was really quite spooky. But we felt very relaxed in such a familiar and well-trodden environment and I think this shows in the playing and the atmosphere of the album. After a month in Nassau, the production was moved to Malibu, California, where the songs were mixed and additional vocals were recorded. On 6 April, Shirley told Blabbermouth.net that he had completed mixing the album, and commented on the final stages of its production on 6 May; "Bruce Dickinson flew in for a few days and sang all his parts before flying off to the four corners of the globe and Steve Harris stayed behind to finish the record with me. He's pretty hands-on like that. Adrian Smith [guitars] dropped in from time to time to hear stuff, and like in any band, not everyone has the same end result in mind, but we get there." Songs The album is the fourth for which Steve Harris receives writing credits for every track, following Killers (1981), Brave New World (2000), and A Matter of Life and Death (2006), although the final track, "When the Wild Wind Blows", is the only song which he wrote on his own. Adrian Smith explains that, in recent years, Harris has become "more into writing lyrics and melodies and arranging" other members' tracks and only "brings in one or two songs" of his own. "El Dorado" was released as a free digital download on the band's official website on 8 June and went on to win in the Best Metal Performance category at the 2011 Grammy Awards. According to Smith, the song's lyrics, penned by Dickinson, are based on the economic recession which began in 2007 and comment on "people's expectations of a better life" and how "the rug [was] pulled out from under them" as a result of lending. The album's first and only music video, containing the latter half of "Satellite 15... The Final Frontier", was filmed in Rendlesham Forest, south-east England, and released on 13 July. Although the album has no official singles, both "El Dorado" and the second part of "Satellite 15... The Final Frontier" (along with its music video) were issued as radio promos before the album's release.
