We have come to the album that Mercyful Fate was best known for "Dont Break The Oath" It contains their signature song "The Oath" as well as many of their greatest works to date. Such as "Come to the Sabbath" and "Desecration of Souls" to name a few. It was very well received And the band quickly became the biggest metal act of the time. This was sadly the breaking point for the band, they separated due to musical differences in 1985 just after the tour.
