Metallica, the frayed ends of sanity.Heavy Metal's most influential voice. With their cross-bred cacophony of punk's jagged anger and rock and roll's monolithic muscle, they've blown apart the temple doors of the once-sacred Top Ten. Their hurricane mosaic of guitar riffs and feverish lyrics has left America gasping for more from these titans of thrash. They've done it all on their own terms, crowning themselves true monsters of rock without compromise. Lars, James, Kirk, and Jason gave imploded any existing ideas about metal and replaced the entire genre with a raw, new staple of rock and roll.
