In 1995, the band sent a free 7″ record to everyone who signed up for the fan club promoted in the liner notes of their debut. Doubling as an apology to those who had received nothing and a promotion for the upcoming album, it came in a plain cardboard colored fold-out with a black-and-white American flag on the cover and the title "Evil Empire" and the band's name all in capitals. On the back was a UPC with marker scribble on the barcode. The A-side was a reissue of the "Evening Session" version of "Bombtrack", listed as "Bombtrack (Live on the BBC)".
