Picture the quintessential rock band. Maybe they’re standing on a grimy street corner with their arms crossed, looking tough, or maybe they’re goofing around in a sunlit field. They could be wearing motorcycle jackets or cowboy shirts or feather boas. They might sound austere and angry or epic and stadium-ready. But what they have in common, regardless of aesthetic, is that they stand together, shoulder-to-shoulder, brothers and sisters in arms. A real rock band is a gang. A group of people united by a shared commitment to what matters in the world, what matters in life, and an insatiable need to communicate that sensibility to anyone else out there who might relate.
