It was the return of Bruce Dickinson and guitarist Adrian Smith (who originally left the band in 1990) in 1999 when Iron Maiden became a six-piece, that established the band's ultimate line-up of Dickinson on vocals, Steve Harris on bass, Nicko McBrain on drums and "the three amigos" – Smith, Dave Murray and Janick Gers - on guitar, heralding a new golden age with the release of Brave New World album in 2000. With both 2003's diverse and ingenious Dance Of Death and its dark and daring follow-up, 2006's A Matter Of Life And Death, Iron Maiden dazzled fans and critics alike. Said Harris, "This is a very intense album in many ways...'Benjamin Breeg' is a great example of the feel of the album in it's really heavy riff and lyrically it's a very dark, atmospheric and powerful song which really epitomizes what the album is all about for us." The epic and ambitious release is also home to fellow classic "Different World."
