Answer
The response "Chester Bennington" is correct. Chester Bennington, the lead vocalist of Linkin Park, tragically passed away in 2017. In the wake of this devastating loss, Mike Shinoda, Bennington's bandmate and close friend, embarked on a deeply personal journey of grief and introspection. This emotional process culminated in the creation of "Post Traumatic," an album that served as Shinoda's way of grappling with the profound impact of Bennington's death.
