Billboard's executive director of music, Jason Lipshutz, chronicles the innovation and influence of this legendary band, from their early childhoods to the moment their paths crossed to the genesis of their iconic first album, Hybrid Theory, and all that followe Linkin Park’s radically vulnerable lyrics also helped usher in a new era of artists (and fans) more open to discussing mental health and prioritizing inclusivity. Led by their front men, Chester Bennington and Mike Shinoda, who balanced each other out artistically, Linkin Park never shied away from songs that put their issues front and center, for the world to see and feel.
