Thrash's titans slow down and hit harder. 'Enter Sandman' opens on that crushing, instantly immortal riff; 'Sad but True' lumbers like a wrecking ball in drop-D; 'Nothing Else Matters' bares an unexpected, aching tenderness; and 'The Unforgiven' marries Morricone gloom to a heavyweight chorus. Bob Rock's polish made them the biggest metal band alive. The album that took Metallica from clubs to stadiums and never looked back.
