Steve Harris
To me, this guy is just about the most "metal" guy of all time. Never cut his hair, always stuck to his guns, never changed his style no matter what shitty popular genre comes along (grunge, nu-metal, metalcore), while other bands like Priest and Metallica gave into the temptation to follow trends Mr Harris just continued to churn out classic metal. Quite simply he has written many of the greatest metal songs of all time (Phantom of the Opera, Killers, 22 Acacia Avenue, Hallowed be thy Name, Where Eagles Dare, The Trooper, To Tame a Land, Aces High, Rime of the Ancient Mariner, need I go on?) Totally dedicated and passionate about the music and the fans.
I probably don't need to mention the man's skillz on the bass guitar.
