Iron Maiden were one of the leaders of the early-1980s New Wave of British Heavy Metal movement energized by the spirit of punk. Maiden built upon their initial cult success, eventually leading to global domination by the mid '80s. The band's singer for the first couple of albums was Paul Di'Anno, but the arrival of vocalist Bruce Dickinson marked the vintage Iron Maiden era. In the '90s, Dickinson was replaced briefly by Blaze Bayley before the classic lineup reunited at that decade's end. Besides the music, Maiden received extra publicity for their undead mascot, "Eddie," who graced numerous album covers, posters, and t-shirts.
