This is a must have!! The music on this CD has inspired many of the great bands of today. From Metallica, who consider Mercyful Fate to be one of their main influences to Megadeth, Alice In Chains and Iron Maiden, who have borrowed certain riffs time and again. For example Iron Maiden took the beginning riff of "Curse of the Pharoahs" and used it in their very popular song "Run to the Hills." This one is a classic because it has the popular Fate songs as they were played originally and live; before the release of Melissa. And Satan's Fall is one of the heaviest and longest songs about Satan that exist. James from Metallica refers to the song as "12 minutes of Satan."
