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.

The band is perhaps best known for their lengthy instrumental songs and large membership. With nine semi-permanent members, they create prolonged tracks which utilize short movements, wide volume changes, and numerous recorded and sampled sounds. Studio albums typically contain no more than five songs, and often omit the band's name and track titles from the cover and artwork.

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. An interview in February 2008 reported the band had broken up, but this was later confirmed as false.

The band will be playing at and curating the All Tomorrow's Parties music festival in the UK in December 2010.

They have also announced their intentions to play "a handful of British and European shows", plus "9 American towns". On the 18th June the first group of these headline shows was announced; a UK tour featuring shows in London, Glasgow, Bristol and Manchester.

 

Their newest album  'Allelujah! Don't Bend! Ascend! was released in 2012.
