7″ Up compiles a dozen singles by obscure UK post-punk bands that heard the DIY call-to-arms in the early Thatcher years. Inside you’ll find great protest songs, comedy, and punchy antidotes to boredom as well as musical and lyrical salvos from future members of The Fall, Public Image Limited, and Pigface. Contact’s “Constant Beat” has a basement-humid groove that’s even funkier than the almighty Gang of Four, and I Jog & The Tracksuits leads a pub sing-along about waiting for something that never happens. The surprise is They Must Be Russians’ lecture on gonorrhea, syphilis, and other delights.
