Today sees the release of "The Metallica Blacklist," a massive new record that features more than 50 contemporary artists laying down covers of every song off of Metallica, a.k.a The Black Album, a.k.a. the 1991 record that made the group internationally famous and saw Metallica cross over into mainstream success. It has been certified 16 times platinum, and it has sold more than 30 million copies worldwide and remains the best-selling album in the United States ever since Nielsen began its Soundscan tracking in 1991. Put it this way: Metallica has never sold fewer than a thousand copies a week since it was released 30 years ago. “The Metallica Blacklist” is a 53-songs of covers in honour of the album’s third-decade anniversary. Metallica’s label is putting out this new collection of covers from a wildly eclectic—sometimes bordering on downright unusual—arrangement of musicians. The names range from pop stars (Alessia Cara, J Balvin) to fellow headbangers (Off!, YB) to Latin music artists (Juanes, Jose Madero) to rappers (Flatbush Zombies) to indie rockers (Diet Cig) and pop super-producers The Neptunes. In one of the oddest collaborations, Miley Cyrus teams up with Yo-Yo Ma, Elton John, Chad Smith from the Red Hot Chili Peppers, producer Watt, and Metallica’s own bassist, Robert Trujillo, for a take on “Nothing Else Matters.” And it’s all for a good cause. All profits from "The Metallica Blacklist" will be split evenly between Metallica’s All Within My Hands Foundation and 50-plus charities chosen by the artists who play on the album.
