9

Mercyful Fate's seventh studio album 9 was released in 1999. Continuing the band's signature occult themes with a heavier, more aggressive, and direct sound, blending their classic melodic style with increased brutality. Featuring tracks like "Sold My Soul", "Burn in Hell", and "Kiss the Demon". 9 would serve as the band's final studio album for 20 years before their 2019 reunion.
