Edge of Thorns is the seventh album by American heavy metal band Savatage, released on April 2nd, 1993 on Atlantic Records. It was the last album to contain the talents of the late guitarist Criss Oliva and it is the first Savatage album to feature Zachary Stevens on lead vocals, following the departure of Jon Oliva from the fore of the band. Also the drums on this album sound different, from other Savatage records, as Steve "Doc" Wacholz decided to use electronic drums. Although most of the drum kits sound authentic, a difference in the sonority of the toms can be heard.
