Mark "The Creeper" Prator drummed as a session drummer on the Iced Earth albums "The Dark Saga" (1996) and "Something Wicked This Way Comes" (1998).
Shortly after the recording of the "The Dark Saga" album, Brent Smedley joined Iced Earth as their drummer. Because he was not available when the band wanted to enter the studio for "Something Wicked This Way Comes", Prator returned on the drum stool during the recording sessions. After they were finished, Smedley returned again until late 1999.
