Mercyful Fate release Don't Break the Oath

Don't Break the Oath is Mercyful Fate's second full-length album.

It was released in 1984.

The style Mercyful Fate employed on Don't Break The Oath resembled a mixture of post-Judas Priest and Iron Maiden heavy metal, lyrically preoccupied with Satan and the occult and distinguished by King Diamond's theatrical falsetto vocals. The album was remastered and subsequently re-issued on Roadrunner Records in 1997. This reissue came with the bonus track, "Death Kiss (Demo)," which would eventually evolve into the album's lead-off track, "A Dangerous Meeting." named this the greatest extreme metal album of all time. All lyrics written by King Diamond.
