When Belfast’s Stiff Little Fingers broke up in early 1983, fans lamented the demise of yet another incredible band from the U.K.’s original punk explosion, 1976-1979. Alongside fellow 1979 debuts by the Ruts (“The Crack”), Undertones (“The Undertones”), U.K. Subs (“Another Kind of Blues”) and an album by the reformed/reconstituted Damned (“Machine Gun Etiquette”), SLF’s astonishing, fiery “Inflammable Material” provided a potent renewal of energy in that last glorious moment before hardcore crashed the punk party.
