Mastodon is honoring the memory of their late bandmate and co-founder Brent Hinds. On Friday (Aug. 22), the heavy metal band paid tribute to the guitarist during a performance at the Alaska State Fair, part of the ConocoPhillips Alaska Concert Series at the Borealis Theatre in Palmer, Alaska.

We had the ups and downs of a 25-year relationship,' said Mastodon's drummer, acknowledging recent tension before Hind's death. '[But] we really loved each other.'
