Bury Your Dead (sometimes abbreviated to BYD) is a five-piece metalcore band that hails from Worcester, Massachusetts, United States. Formed in 2001, Bury Your Dead began as a side project of the band Hamartia featuring Brendan "Slim" MacDonald (guitar) and Mark Castillo (Drums). With the metalcore sound of Hamartia growing tiresome to both Slim and Mark, they started writing less technical songs in their free time. They recruited Steve Kent to play bass, second guitarist Jesse Viens, and Joe Krewko as vocalist and began playing shows in Massachusetts and Connecticut under the name Bury Your Dead.
