Brent Hinds Estate Clarifies Legal Action Against Mastodon Members

The estate of Brent Hinds released a new statement to Guitar World magazine to address the public discourse surrounding its lawsuit against the members of Mastodon. The legal action, filed on September 3 in Fulton County Court, centers on claims that the late guitarist was never properly bought out of his share in the band's business entities. The estate's latest communication seeks to move the focus away from rumors of a "windfall" and toward what they describe as an orderly separation of interests that was never completed before Hinds’ death in August 2025.

"Unfortunately, public discussion has largely focused on Mastodon’s inclusion of Brent’s image in artwork for a new album and has sometimes portrayed the lawsuit as an effort by his family to obtain a windfall. That is not what the case is about."

The estate further explained that after Hinds was excluded from the Progressive Metal group in March 2025, he had sought a valuation and accounting of his interests.

"After Brent was excluded from Mastodon, he sought an accounting, valuation and orderly separation of interests he held in entities owned by the founding members. He passed away before that process was finished…Brent had not yet received compensation for any of his interests,"

Financial Disputes and the Uncashed Check

According to reports from The Atlanta Journal-Constitution, the civil complaint reveals that the surviving members of Mastodon—drummer Brann Dailor, bassist Troy Sanders, and guitarist Bill Kelliher—provided a check for $80,000 to the estate as a buyout. However, the estate alleges that there was no transparent accounting provided to explain how the band reached that specific valuation. Consequently, the estate has declined to cash the check until a full audit determines the actual value of Hinds' stake in the various band-related companies.

The lawsuit also highlights the usage of Hinds' likeness on the cover of the band's recent album, "Marrow Deep". Although Hinds did not perform on the record, a recognizable image of his face appears on the artwork, which depicts the Three Fates of Greek mythology. According to the lawsuit, the image of Hinds is visible amongst the skulls in a garment worn by the Fate identified as Atropos. The estate contends that using Hinds’ image for marketing purposes while denying his ongoing entitlement to merchandising revenue is a "broader commercial issue."

"The remaining members maintain that Brent did not participate in Mastodon’s new album, yet the band chose to use a recognizable image of him to market that album and did so without the estate’s consent. This illustrates that Brent remains relevant to Mastodon’s brand even after his exclusion and death."

The Split and "The Mastodon In The Room"

Mastodon and Hinds ended their 25-year partnership in early 2025. While the band’s initial public statement described the split as a mutual decision, Hinds later contested this on social media, referring to his former colleagues as "horrible humans" and attacking their vocal abilities and vanity. The tension has been further exacerbated by the release of a 35-minute documentary titled "The Mastodon In The Room". In the film, Dailor, Sanders, and Kelliher discussed Hinds' exit and death, implying that his struggles with substance abuse played a role in his departure.

The estate’s lawsuit criticizes the band for disclosing private details that Hinds had chosen to keep confidential during his life. While the band members expressed unhappiness that what they considered a "private business matter" had been made public, they have stated their intention to defend themselves "vigorously" against the allegations and denied any ill intent.

Circumstances of Hinds' Passing

Brent Hinds died at the age of 51 following a motorcycle accident in Atlanta on August 20, 2025. According to police reports, Hinds was riding a Harley-Davidson when he was struck by an SUV at the intersection of Memorial Drive SE and Boulevard SE. While the other driver failed to yield, investigators eventually determined Hinds was at fault due to speeding. Video evidence suggested he was traveling between 63 and 68 mph, approximately double the posted speed limit at the site of the crash.

In their concluding remarks, the estate called for an end to the "personal attacks and harassment" directed at Hinds' family members based on speculation.

"The estate maintains that the band cannot fairly invoke Brent’s identity when it is commercially useful, while simultaneously denying the continuing relevance of his contributions when accounting for his interests,"

The statement emphasizes that the legal process is not intended to ask the public to choose sides or diminish the music the band created together, but to ensure a fair resolution of Hinds' legacy and interests while calling for "compassion and respect."
