The song was co-written with Eg White and was released to US contemporary hit radio on October 3, 2017, as the album's third and final single.

Later on, the band revealed the friend was Amy Zaret,[8] a 25-year veteran of Warner Bros. Records who died in October 2015 following a cancer diagnosis.

It's a sad song, but the pay-off is that when something dramatic and painful like that happens, the most important thing to do is to connect with the people you love and remind them you care about them.

[11] After lead singer Chester Bennington's suicide on July 20, 2017, the band selected "One More Light" as their next single.

The official video was uploaded to Linkin Park's YouTube channel on September 18, 2017, and directed by Joe Hahn and Mark Fiore.

As we move forward to the Hollywood Bowl show and beyond, I think about the people that connect with the band, outside and inside our circle.
