Edge of Sanity began as a death metal band with their debut release
Nothing but Death Remains. The band's second release,
Unorthodox, with tracks like "Enigma" and "When All Is Said", showed Edge of Sanity branching out from some of the genre's conventions and striving for a more progressive sound. With
The Spectral Sorrows,
Until Eternity Ends, and
Purgatory Afterglow , the band continued its tendency towards longer and more melodic songs. By the release of
Crimson in 1996, Edge of Sanity was well established
progressive death metal band.
Crimson was a 40-minute
concept album consisting entirely of one track, concerning a
post-apocalyptic future in which mankind had lost the ability to breed. After the release of
Infernal in 1997, founder Dan Swanö left the band, citing creative differences with guitarist Andreas Axelsson. Following Swanö's departure, Axelsson hired Robert Karlsson, the vocalist of
Pan.Thy.Monium, a
side project in which Swanö was also involved, and released
Cryptic in 1997. Despite the efforts to keep the band running, the band split up shortly after the release of
Cryptic. In 2003, Swanö revived the outfit as a one-man band with several session musicians, and recorded a sequel to
Crimson,
Crimson II. Immediately after, he re-dissolved the project. In 2011, Swanö re-released the
Kur-Nu-Gi-A demo as a LP, and a CD edition of it in 2012. In April 2024,
Century Media Records and
InsideOutMusic unveiled plans to reissue both remixed and remastered editions of the band's catalogue, reworked by Dan Swanö himself. Along with the announcement, Century Media released a remix of "Twilight", from the band's 1994 album
Purgatory Afterglow, plus a music video for the new track. The reissues were released in "chapters" throughout 2024 and 2025, along with remastered versions of
Nightingale's records. In June 2024, Century Media released the first chapter of reissues, featuring
Purgatory Afterglow as well as the band's only EP, 1994's Until Eternity Ends, along with a music video featuring the remastered version of "Black Tears"
