We have two significant birthday celebrations this week as Iron Maiden’s Bruce Dickinson turns 68 on August 7, while Metallica’s James Hetfield celebrates his 63rd birthday today (August 3). These two musicians are among the biggest names in metal, and this week in Chuck’s Fight Club on the Loudwire Nights radio show, we will let them battle it out for a special birthday boy block of songs. So, who is your preferred metal frontman?

On one side, we have Iron Maiden’s Bruce Dickinson, one of the most energetic live performers in metal. He consistently brings a commanding presence to the stage while delivering iconic tracks such as “The Number of the Beast,” “Run to the Hills,” “Infinite Dreams,” “Flight of Icarus,” “The Trooper,” “The Wicker Man,” and “Writing on the Wall,” among others.

His competitor is Metallica’s gritty centerpiece. Wielding underrated guitar skills and a fierce vocal delivery, Hetfield commands your attention onstage. He has been the voice throughout their career, from “Battery,” “Master of Puppets,” “Fight Fire With Fire,” “Enter Sandman,” “One,” “Fuel,” “Lux Aeterna,” and many more favorites.
