You must the most undereducated person ever.
For anyone interested in music of substance, the metal scene of the early '80s was a pretty bleak place, dominated by cheesy hair bands hawking bubblegummy rock that had been dolled up with beefy guitars and naughty lyrics. Metallica, along with contemporaries like Megadeth and Anthrax had something altogether different in mind. Influenced by punk principles of raw musical directness and lyrical focus fraught with a dark and brooding idealism, they helped lay the groundwork for a whole new era of metal.
Metallica was so huge that mainstream media could no longer ignore the phenomenon; it went multi-platinum, tipped their previous albums into platinum status and won them their third Grammy.
ICP on the other hand has so many good records that u wouldnt know wut to do wit.The most consistent album the great malienko Despite virtually no radio airplay and no MTV play whatsoever, the album quickly went gold and secured these horrific.
SO IF U CRACKERASSED FREAK WHO THINKS METALLICA SUCKS AND ICP IS A BUNCH OF CLOWNS WHO DONT CARE WELL GO GET SUM SATELITE TV N WATCH SUM MTV OR SUMTHIN PLEASE.
