Back on Thursday, it was reported that Chester Bennington, the lead singer of Linkin Park, had died; the cause was suicide via hanging:
Soon afterwards, there was a huge outpouring of grief on social media. Many people, including a large number of my friends, had been touched by the music Bennington had sang with Linkin Park; the band's music frequently contained references to depression and personal pain, as influenced by Bennington's own experiences. As such, Linkin Park's music was highly relatable for many and helped people with their own troubles.
In my case, Linkin Park were among the musical acts I first heard when I started listening to the radio back in late 2004, as that was when "Numb/Encore", from the Linkin Park/Jay-Z mashup album Collision Course, was released. My brother has Linkin Park in his music collection but we both like the band.
The BBC has an obituary about Bennington, which can be found here.
