Iron Maiden fans who have waited three years for a new live album from the band can rejoice with 'En Vivo,' which was released on March 27 on CD, Blu-ray, DVD and picture disc vinyl. One lucky reader of Ultimate Classic Rock will win a special package containing all four formats.

'En Vivo' captures the April 10, 2011 show at the Estadio Nacional in Santiago, Chile during Maiden's 'Final Frontier' world tour. The concert was filmed with 22 HD cameras capturing the band in action, as well as an octocam, which flew above the crowd and recorded the 50,000 fans in attendance.

The first disc is comprised mostly of songs from 2010's 'Final Frontier' album, including 'Coming Home' and 'El Dorado,' with a couple of classics, '2 Minutes to Midnight' and 'The Trooper' thrown in for balance. Disc Two finds them going through their back pages, with five of its eight songs coming from their classic 1980s output, such as 'The Number of the Beast' and 'Running Free.'

The Blu-ray and DVD editions contain one hour and 42 minutes of bonus features, including 'Behind The Beast,' a documentary of the tour and the director's cut of the video for 'Satellite 15...The Final Frontier.'
