Who Is Brann Dailor?
Brann Timothy Dailor is an American musician whose primary instruments are drums and percussion, although he has also contributed vocals, bass, and keyboards to various projects. He is particularly recognized for combining complex progressive-rock drumming with the heavy sound of Mastodon.
Dailor’s professional music career began well before Mastodon. During his early years, he played in several bands and developed a reputation as a highly skilled drummer. His work eventually led him to Atlanta, where he became one of the founding members of Mastodon.
Brann Dailor and Mastodon
Dailor formed Mastodon in Atlanta in 2000 alongside guitarist Bill Kelliher, bassist Troy Sanders, and guitarist and vocalist Brent Hinds. The group became known for combining heavy metal with progressive and experimental influences.
As Mastodon’s drummer, Dailor became an important part of the band’s distinctive rhythmic style. He also gradually took on a larger vocal role.
The band’s early albums established its reputation within the metal scene, beginning with Remission in 2002. It was followed by albums including Leviathan, Blood Mountain, Crack the Skye, The Hunter, Once More ‘Round the Sun, Emperor of Sand, and Hushed and Grim.
Drumming Style
Dailor’s drumming is one of the defining elements of Mastodon’s music.
His style combines speed, technical precision, unusual rhythmic patterns, and progressive-rock influences. Rather than relying exclusively on conventional heavy-metal beats, he frequently incorporates complex fills and changing rhythmic structures into Mastodon’s songs.
His influences include musicians such as Phil Collins, Neil Peart, Sean Reinert, Mikkey Dee, Dave Lombardo, Elvin Jones, Tony Williams, Billy Cobham, and Bill Bruford.
These influences help explain the mixture of progressive rock, jazz-inspired ideas, and heavy metal found in his playing.
Dailor as a Vocalist
Although Dailor is primarily known as a drummer, he is also one of Mastodon’s vocalists.
His vocal contributions became increasingly prominent during the band’s career. One notable example is “Oblivion,” from the 2009 album Crack the Skye. The song featured Dailor alongside Troy Sanders and Brent Hinds as vocalists.
His role as both drummer and vocalist gives him a distinctive position within Mastodon. Performing demanding drum parts while contributing vocals requires considerable coordination and has become an identifiable aspect of the band’s live and recorded performances.
Early Musical Career
Before Mastodon, Dailor was involved with several bands.
He played with Lethargy, an experimental metal band, and also worked with Today Is the Day. His earlier projects helped establish the technical and progressive approach that would later become a major part of Mastodon’s sound.
Dailor’s early musical experiences also connected him with other musicians who would become influential in the American metal and alternative music scenes.
Arcadea
In addition to Mastodon, Dailor has been involved with Arcadea, a progressive and experimental rock project.
Arcadea was formed with Dailor, guitarist Core Atoms, and keyboardist Raheem Amlani. The group released its self-titled album Arcadea in 2017, with Dailor contributing drums and vocals.
The project allowed Dailor to explore a different musical direction from Mastodon’s guitar-driven heavy metal.
Songwriting and Creative Contributions
Dailor is also a songwriter and has contributed to Mastodon’s broader creative process.
His songwriting role is particularly visible in songs where personal experiences and emotional themes become central to the band’s music. He has also contributed lyrics and vocals alongside his instrumental work.
This combination of drummer, vocalist, and songwriter makes him more than simply the percussionist within Mastodon.
Grammy Recognition
Dailor is a Grammy Award winner as a member of Mastodon.
The band won the 2018 Grammy Award for Best Metal Performance for “Sultan’s Curse.” Dailor discussed the award and the song with the Recording Academy, explaining the significance of the track and its connection to Mastodon’s Emperor of Sand era.
The Grammy marked an important achievement in Dailor’s career and recognized Mastodon’s contribution to contemporary heavy metal.

Mastodon subsequently continued with Dailor, Troy Sanders, and Bill Kelliher, alongside guitarist Nick Johnston and keyboardist João Nogueira for performances and recordings.
The changes also influenced Mastodon’s subsequent music.
In 2026, Dailor and Sanders continued sharing vocal duties as the band entered a new chapter following Hinds’ death. The song “Your Ghost Again” became particularly associated with Dailor’s reflections on loss and the band’s history with their former bandmate.
Marrow Deep and Mastodon’s 2026 Era
