Although newer My Chemical Romance fans may be more familiar with the group’s current drummer, Jarrod Alexander, Bryar played a musical part in the group’s rise in popularity. Alongside the band’s original members and lead vocalist Gerard Way, Bob Bryar played on MCR’s breakoutout album, The Black Parade.

In 2023, Bryar publicly opened up about mental health struggles, per The Independent.

One of the drummer’s final X posted mentioned Linkin Park’s late lead singer Chester Bennington, who died by suicide in 2017.
