This is the Clash album you should listen to. Forget any compilations of singles or whatever. Forget “Rock the Casbah” and “Should I Stay or Should I Go” for now. Listen to this album and feel these songs make the hairs on your arms stand up. This is the Clash’s punk album. It is also the best selling album import in the U.S. (yes, it’s not the Beatles). This is the real British invasion.
