Godspeed You! Black Emperor is a Canadian post-rock band that originated in Montreal, Quebec in 1994. The group releases recordings through Constellation, an independent record label also located in Montreal. After the release of their debut album, F♯ A♯ ∞, in 1997, the group toured regularly from 1998 to 2003. Their second album, 2000's Lift Your Skinny Fists Like Antennas to Heaven, received critical acclaim and has been named as one of the best albums of the decade. This was followed by 2002's Yanqui U.X.O. In 2003, the band went on hiatus in order for members to pursue other musical interests. In the intervening period, the group was occasionally rumored to have broken up, but eventually reconvened in 2010. Since reforming, they have released four more albums: 'Allelujah! Don't Bend! Ascend! (2012), which won the 2013 Polaris Music Prize; Asunder, Sweet and Other Distress (2015); Luciferian Towers (2017); and G_d's Pee at State's End! (2021).

Post-rock is a form of experimental rock characterized by a focus on exploring textures and timbres, as well as non-rock styles, with less emphasis on conventional song structures or riffs. Post-rock artists typically combine rock instrumentation with electronics. The genre emerged within the indie and underground music scene of the 1980s and early 1990s. However, due to its abandonment of rock conventions, it began to increasingly show little resemblance musically to conventional indie rock at the time, borrowing instead from diverse sources including ambient, electronica, jazz, krautrock, dub, and minimalist classical, with these influences also being pivotal for the style of ambient pop.
