Gary Parker has 1 Mercyful Fate concert.

Mercyful Fate is an influential heavy metal band that formed in Copenhagen, Denmark in 1981 from the remaining members of Hank Shermann's band Brats and King Diamond's band Black Rose. In early 1981 they helped out Michael Denner with demos for his band Danger Zone. Soon, Shermann, Denner, Diamond, and Denner's bass player Timi Grabber realized their potential as a unit and started performing as Mercyful Fate. The band experienced the usual member changes for a new band, as Denner left (and later returned).
