Biffy Clyro and OFF! have both dropped their own extremely different covers of Metallica's self-titled "Black" album track "Holier Than Thou."

The bands are among the 50-plus artists who have contributed to the Blacklist tribute album — a collection of "Black" album covers by a wide variety of artists, which will be released on the same day as the massive reissue of Metallica's historic and game-changing 1991 record.

This pair of covers arrive on the same day Metallica debuted a 1990 pre-production rehearsal recording of "Holier Than Thou," which is among the album's more thrash-oriented cuts. OFF! naturally play into this speedier direction with their brand of hardcore punk, meanwhile Biffy Clyro have completely overhauled the track with their synth-charged, prog-tinged pop-rock take.

Listen to both cover songs below and see the complete Blacklist track listing at the bottom of the page. Look for the tribute album to be out Sept. 10 in tandem with a reissue of the 'Black Album.'
