Metallica is turning result in 1991 with the Black Album by abandoning his unbridled speed metal and powerful that it still produced four years earlier with the album And Justice For All And released in 1988. So that's the famous 5th album much-maligned, but why? the group changed its style, it slows down the tempo, creating great melodies, remains in a very heavy and powerful register, Kirk Hammet fills us with guitar solos and lots of effects wrought, the rhythm section, precise and compelling firmly supports ALL OPERATING and James Hetfield has never sang as well. So what you want? How are not tuned to vibrate these unstoppable titles "Enter Sandman" "" Sad But True "" The Unforgiven "or the beautiful" Nothing Else Matters "! Metallica expanded its audience, lost speed metal fans but gained the dheavy tough and original rock fans, it turned challenged with reason and confirm its creative potential with the album "Load" and "Reload". A superb album sound great product beautifully by Canadian Bob Rock who sest as busy Mötley Crüe, Bon Jovi, The Cult and many others (12 tracks / 62mn39).
