Godspeed You! Black Emperor (formerly punctuated Godspeed You Black Emperor! and commonly abbreviated to GYBE or GY!BE) is a Canadian post-rock band which originated from Montreal, Quebec in 1994. They were the first outside act to release their recordings through Constellation, an influential independent record label also located in Montreal.
After the release of their debut album in 1997, the group toured regularly from 1998 to 2002. In 2003, the band announced an indefinite hiatus in order for band members to pursue other musical interests. In the intervening period the group was occasionally rumored to have broken up, but the band finally reconvened for a tour in late 2010 and early 2011.
