Stronger Than Ever is the fourth studio album by German heavy metal band Grave Digger. However, they changed their name to just "Digger" for this release. Retrospect Records, a little-known record label, very briefly issued a re-release of the album on CD in 2005. The CD was released with presumably no involvement from the band and is considered a bootleg. The CD is no longer available and the only official versions of the album that were released by the band are the vinyl and cassette versions. To this day it remains the only album in Grave Digger's catalog to not receive an official CD release. "Shadows of the Past" borrows two lyrical lines from "Yesterday", a song released on their 1984 album Heavy Metal Breakdown.
