Kim Ruzz, also known as Kim Thyge Jensen, was the initial drummer in Danish metallers Mercyful Fate when they started in 1981. The band added drummer Bjorn T. Holm to the line-up in early 1996 for the 'Into The Unknown' album.
More recently, Kim Ruzz drummed with Metalruzz until he decided to stop his involvement in the Danish heavy metal band in January 2014 due to "physical limitations".
