Black Market Clash was released in October 1980, only in the US and Canada, in between London Calling and Sandinista!. It compiled recordings which were then unavailable in the US except as imports. The disc was one in the series of "Nu-Disk" 10-inch records from Epic. Other artists in the series included New Musik and Cheap Trick. "The Prisoner," the cover of "Pressure Drop" by Toots and the Maytals, "City of the Dead," and "Armagideon Time" had all been UK b-sides from the period 1977–79, respectively of "White Man in Hammersmith Palais," "English Civil War," "Complete Control," and "London Calling."
