In its 30th anniversary year, Metallica’s Master of Puppets is the first metal album to have been preserved by the US Library of Congress for its historical significance.

In a statement from the establishment, the album was described as “show[ing] the group moving away from its thrash-metal history and reputation and exploring new ideas.”

The album has been added to the National Recording Registry, which celebrates sound recordings that are culturally, aesthetically or historically important.
