For metal-loving Southern Californians, The Battle of San Bernardino was this Summer’s hottest event. On a lucky Friday the 13th (August), seven heavy bands, Warbringer, Overkill, Sabaton, Testament, Anthrax, Megadeth, and headliner Iron Maiden performed at a venue well-known for its big outdoor festivals. Testament and Anthrax played extraordinary sets, Megadeth shined, but it was the headliner, Iron Maiden, that blew minds. A killer set highlighting the ‘Seventh Son of a Seventh Son’ album, it was classic Maiden, playing in top form.
