The mosh pit has a reputation as a violent place where (mostly) white guys vent their aggression. There’s some truth to that, but it’s also a place bound by camaraderie and—believe it or not—etiquette. In this episode, we explore the unwritten rules of this 50-year-old, live-music phenomenon with punks, concertgoers and a heavy metal physicist.
