Crimson is the fifth full-length studio album by Swedish death metal band Edge of Sanity, which is their first concept album and was released in 1996 by Black Mark Production. It features a single 40-minute track, telling a story in the distant future, when human civilization is about to end. While the album was originally pressed on vinyl upon release in 1996, it was later reissued with Crimson II as a double vinyl in 2003. This version splits the song in half, the parts running 18:38 and 21:04 respectively.
