"Black Cross" is 45 Grave's debut single. It was not featured on an album but was later included on "Autopsy", and remains a staple of their live performances. It is a good example of 45 Grave's style: a blend of goth and punk rock.
The b-side, "Wax," was likewise never featured on a studio album, but saw release on "Autopsy". "Wax" differs from other early works by 45 Grave as it dips more into the heavy metal genre, creating a slow, atmospheric, heavy goth song.
