Some of those hard livin' metal-heads chalk up the demise of metal in the late 80s to the self-absorbed equivocating of the kids fronting grunge bands. Grunge, an offspring of heavy metal, spoke the language. Headbangers & politicians know: you must speak the language if you wanna' get to... Recently, Congressional pols have been ignoring this rule. Take the immigration debate; it's headed for a major collision, in part, because there are a few too many metal heads in the Senate.
