Slayer and Austin thrashed supreme this last decade. The SoCal metal pioneers (b. 1981) upended Auditorium Shores twice for Fun Fun Fun Fest, 2011 and 2013, then picked up at the Moody in 2014 and 2016 – all without founding guitarist Jeff Hanneman. For their swan song, Lamb of God, Anthrax, Testament, and Behemoth form a salutary circle of respect, gratitude, and extremity. – Raoul Hernandez
