To celebrate their latest album, 72 Seasons, Metallica is shaking up the format of its tour. Instead of performing one night at each venue, the pioneering metal band is doing two nights back-to-back, each with totally different set lists, different supporting acts, and a strict promise to not play the same song twice in each city. They've also reimagined the structure of the stage itself. Rather than playing at one end of the stadium, they're performing on a giant, donut-shaped platform amid the fans (diehards can stand in the center, an area aptly titled the Snake Pit). In other words: headbanging heaven. Whether you're prepping for an upcoming show or reminiscing about one you recently attended, explore the tour-inspired set list here and put yourself in the pit.
