Brent Hinds, who won a Grammy with Mastodon in 2018, just torched his old crew in public.
On Tuesday, June 24, the popular heavy metal band — now made up of Troy Sanders, Brann Dailor, and Bill Kelliher — marked the 11-year anniversary of Once More ’Round the Sun by posting the album art on Instagram. “11 more trips ‘round the sun since this was released!” the caption read.
At first, the comments section was filled with love. Fans shared favorite tracks and memories, with many praising the band’s past work. But one fan dropped a bittersweet note: “Halloween is definitely my #1 track… definitely gonna miss B. Hinds though.”
That’s when things went south. “I [won’t] miss being in a s*** band with horrible humans,” the 51-year-old former Mastodon guitarist wrote from his personal account, replying directly under the post. The comment has since vanished, but screenshots lit up social media within minutes.
“Brent is an unbelievable d-bag and the fact that he’s posting petty Instagram comments is embarrassing. He wrote some of my favorite music, but he’s a complete mess,” one person wrote on Reddit.
“No wonder they kicked him out, gotta be so hard to work with an adult baby like Brent. How far he has fallen, in my eyes,” another said.
“This dude needs therapy,” chimed in a third.

Others were more sympathetic.
“To be fair, he cofounded and was with the band many years. Like a long marriage that finally comes to end in divorce, it’s gonna haunt him for a long while,” one fan pointed out.
“People are too invested,” someone else said. “Nothing can take away the impact this guy had on the guitar world. Nobody really knows both sides. Seems to me Mastodon became more of a business rather than a band.”
For those out of the loop, Mastodon and Hinds officially parted ways in March after 25 years together.
The announcement, shared via Instagram, painted the split as mutual and drama-free.
“We’re deeply proud of and beyond grateful for the music and history we’ve shared,” the band wrote at the time. “We wish him nothing but success and happiness in his future endeavors.”
