The Erosion of Sanity is the second full-length album by Canadian technical death metal band Gorguts. The album was released on January 19, 1993, through Roadrunner Records. Though it is now considered a milestone in the genre, the album's release coincided with the decline of death metal's popularity as a genre, and Roadrunner decided to drop the band from their roster. The band subsequently entered into a five-year state of limbo in which they ceased touring, during which all members except Luc Lemay left. Gorguts later returned with a new lineup, releasing their third full-length album Obscura in 1998.
The album was remastered and re-released with Considered Dead as part of Roadrunner's Two from the Vault series, in 2004. It was re-released again in 2006 with two bonus tracks.
