Longtime Mastodon manager Nick John has died following a battle with pancreatic cancer. The news was confirmed via an Instagram post from the band's guitarist/vocalist Brent Hinds, which contained a picture of John and a caption that read "RIP Nick John" with a broken heart emoji.

As Blabbermouth reports, rock photographer Andrew Stuart also shared a social media post in remembrance of John. "Still not computing that this day is actually real," he wrote on Facebook. "Rest easy Nick John. I’m honored to have spent over 15 years working with you, learning from you and becoming your friend. You’ll always live on as family, I love you dude. Fuck fuck fuck cancer. Hug all your people. Hug all animals. Love music. Extra love to Nick’s wife Colleen, The RSE camp especially my sister/wife Kristen, Mastodon, Gojira and every artist who’s life and career was touched by Nick."

News of John's diagnosis broke last week after Hinds and Brann Dailor shared social media posts on his status. "Help send all the power and love of the universe to our dear friend and manager Nick John," Dailor said in a post to his page. "I don't know where Mastodon would be without him. He is absolutely integral to the success we have achieved as a band not to mention one of the best people you'd ever hope to meet. We all deeply love and care for him. Send your love his way. Thank you."

The comments came just days after the band announced they would be canceling a 13-date run with Dinosaur Jr. and Netherlands "due to a critical situation of a member of the Mastodon family."
