EN VIVO! was filmed on 10th April 2011 in front of over 50,000 ecstatic fans at the Estadio Nacional, Santiago during the Round The World In 66 Days leg of The Final Frontier World Tour, and captures a magnificent performance by the band, ardently embraced by the legendary Latino passion and energy of their Chilean fans. With spectacular stage backdrops, dynamic musicianship and a literally jaw-dropping appearance by Eddie, this live show encapsulates to perfection the heart and soul of Iron Maiden 2011. The concert was filmed digitally using 22 HD cameras and an octocam, recorded in both stereo and 5.1 audio and mixed by Maiden's longstanding producer Kevin "Caveman" Shirley, all of which serves to accentuate the incredible atmosphere of this compelling performance.

Extensive use is made of split screens so fans can follow the individual members closer and the set list moves seamlessly between songs from Maiden's most recent studio album, 2010's The Final Frontier through to classic fan favourites via the band's vast and varied catalogue. DVD Disc Two features an 88-minute documentary, BEHIND THE BEAST, a revealing high quality "home movie" for the fans showing them how to put on an Iron Maiden tour and what goes on behind the scenes at a show. It describes the extraordinary story of one of the most acclaimed and ambitious touring shows in the world.

In addition to interviews with the Iron Maiden crew, it interweaves anecdotes from the band and their fans, and includes footage of the live show. The bonus disc also contains an extended version of the promo video "Satellite 15.The Final Frontier", a video about the making of "Satellite 15.The Final Frontier" plus the opening video sequence to The Final Frontier World Tour. Maiden's "Final Frontier World Tour 2010-11" saw the band circumnavigating the planet for the third time in their customized Boeing 757, Ed Force One, piloted by lead singer Bruce Dickinson, and playing 98 shows in 36 countries to over 2 million fans.
