This Blu-ray filmed on April 10, 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 encapsulates to perfection the heart and soul of Iron Maiden 2011. The concert was filmed digitally using 22 HD cameras and an octocam (a flying camera which captures aerial crowd scenes), 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 screen so fans can follow the individual members more closely, and the set list moves seamlessly between songs from Maiden's most recent studio album, 2010's The Final Frontier, through to classic fan favorites via the band's vast and varied catalog. DVD #2 is a bonus disc containing an 88-minute documentary, Behind the Beast. This is also an entirely in-house production by Maiden's own Krew, led by Andy Matthews, and is intended as an interesting and revealing high quality "home movie" for their fans to see how Iron Maiden put on a tour and what goes on behind the scenes at a show.
