Stiff Little Fingers led the punk rock charge in Ireland in the ‘70s. The political violence tearing the country apart pulsed through the Belfast band's bloodstream, and their songs swelled with an urgency that was impossible to ignore. Mere teens when they started, the band evolved at a startling pace; by the early ‘80s, they were incorporating everything from folk flavors to dashes of psychedelia into their sound, while still coming across as completely uncompromising. It's no wonder they've been a key influence on everyone from Rancid to U2.
