Chris Martin led tributes to the late Chester Bennington on Tuesday night as his band, Coldplay, kicked off the North American leg of their tour.
The band were performing at the MetLife Stadium in New Jersey in front a packed crowd; including Linkin Park member, Mike Shinoda.
During the show, Martin paused to pay tribute to Bennington who took his own life at his home in LA on July 20.
After a false start, Martin stopped and told the crowd: "I know this is probably going to end up on YouTube so I want to do it right."
He performed a piano version of the famous Linkin Park song, Crawling.
Shinoda took to Instagram after the gig to show that he was there, watching on, and described the choice of song, and the performance, as 'beautiful'.
"Thank you Coldplay," he wrote. "It sounded beautiful."
Shinoda was one of the founding members of Linkin Park, which he formed with fellow high school friends in 1996, with Chester joining later as lead vocalist.
Last month, it was announced by Shinoda that Chester had died, with the band making a heartbreaking tribute in the hours after.
"Dear Chester," it read. "Our hearts are broken. The shockwaves of grief and denial are still sweeping through out family as we come to grips with what has happened.
"You touched so many lives, maybe even more than you realised. In the past few days, we've seen an outpouring of love and support, both public and private, from around the world."
Bennington had been suffering with a mental illness battle for some time, and opened up about depression in a recent interview.
The 41-year-old said: "I came to a point in my life where I was like, 'I can either just give up and fucking die or I can fucking fight for what I want'.
"And I chose to fight for what I wanted. I wanted to have good relationships. I wanted to love the people in my life. I wanted to enjoy my job."
Even in the days leading up to his death he seemed to be 'doing great', according to one close friend of his.
Bennington's death shocked millions around the world, but once again opened up the debate of mental health issues in society. It's important that we talk up and speak out about them.
If you or someone you know is struggling with issues, don't suffer in silence. Reach out. It's the brave thing to do.
