Edge of Sanity was a Swedish death metal band fronted by musical genius Dan Swano, who is renown among the metal underground for all the numerous musical projects he has fronted and also for his work as a producer. The band is commonly regarded alongside Opeth as being the first to combine Extreme metal styles like Death and Black Metal with genuine Progressive rock. Eveantully culminating in the release of the album Crimson, a single 40 minute conceptual song dealing with a post apocalyptic future in which mankind has lost the ability to breed.
The band split up in 1999 and was briefly revived by Dan Swano in 2003 as a solo project, releasing Crimson II a direct sequel to Crimson, but after that the project was dissolved and has remained quiet ever since.
!!Edge Of Sanity provide examples of:
* ConceptAlbum: Crimson and Crimson II, [[CaptainObvious obviously.]]
* EpicRocking: Crimson as well as it's sequel are both 40 MINUTES long and take up the entire album.
* IAmTheBand: Dan Swano on the sequel to Crimson, he performed every single instrument as well as all the vocals. Justified as the band had broken up by that point.
