Godspeed You! Black Emperor is a Canadian post-rock band formed in Montreal in 1994. Known for their expansive, cinematic soundscapes, they blend elements of classical music, punk, and ambient noise to create instrumental compositions that often exceed 20 minutes. Their music is politically charged and frequently accompanied by film projections during live performances. The band operates as a collective, with a rotating lineup and a strong DIY ethic, rarely giving interviews or engaging in traditional promotion. They're widely regarded as pioneers of the post-rock genre.
