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.

The Spectral Sorrows, Until Eternity Ends, and Purgatory Afterglow continued the trend, so that by the release of Crimson (1996), Edge of Sanity was a progressive metal band.

After one more album, Infernal (1997), guitarist/vocalist/songwriter Dan Swanö left Edge of Sanity, and his departure is generally associated with a decline in quality in the band's material.

In the spring of 2024, Century Media Records and InsideOutMusic revealed plans to launch the first chapter of an extensive reissue campaign for Edge Of Sanity's catalogue.
