Iron Maiden vocalist Bruce Dickinson discussed the making process of group's signature "The Trooper" beer, calling brewing an artform of its own. During a chat with CNN, the frontman insisted the metal icons had a reputation to maintain, turning "The Trooper" into a true challenge. "The original idea was that they'd just slap a label on it," Bruce explained. "We can't do that, we've got a reputation to keep up; anyway, I like beer - why don't we really, properly create our own brew?" Dickinson continued, "I wanted a beer that post above its weight in terms of flavor, but which didn't knock you on your a-s in terms of alcohol content. Real beer is not an industrial process, it's more than that because it is genuinely an art. The bitterness content of the hop changes every season, so how do you make a beer that tastes the same when the ingredients change every year?" Finally, the singer addressed the skeptics saying that signature Maiden beer is a gimmick, saying they're not something the band bothers with. "They obviously haven't drunk it," he said. "We have the power of brand of Iron Maiden, but if you open the bottle and you taste the beer and you go blargh, that's the end of your branding. And that reflects really badly on us." Although he is known for his entrepreneurial spirit, the latest stories of Dickinson being hired to manufacture drones for the US military had everyone quite surprised. The reports were instantly squashed by the vocalist's spokesperson, describing them as "totally inaccurate and malicious." After lat week's (September 13) San Bernardino performance, Iron Maiden are rumored to be planing their own festival. Apart from Maiden, the show itself also featured Megadeth, Testament, Anthrax, Sabaton, Overkill and Warbringer.
