Few bands—if any—can claim the FBI has arrested them as suspected terrorists. The nine or more members of the post-rock orchestra Godspeed You! Black Emperor can, and they don’t exactly wear the arrest as a mark of shame but rather as a badge of honor. As self-described anarchists with a strong penchant towards anti-corporatization, the loose collective from Montreal, Quebec weave instrumental pieces of dense repetition, found sounds, traditional rock instrumentation and cobbled bytes covering everything from homeless street preachers to obscure transistor radio broadcasts into their music. If there was a psychedelic post-apocalyptic Halloween party with arsenic spiked Kool-Aid, chances are GYBE would be the house band.
