In 1992 SEPSISM recorded their first demo, giving the local scene a long awaited release and spreading the band's unique style throughout the worldwide underground. In 1993 after enlisting guitarist Leon Morrison, SEPSISM returned to the studio to record their second demo. Along with countless shows and underground press Sepsism was becoming one of the most well known California Deathmetal bands. In 1994 Sepsism again entered the studio to record their third demo, SEVERE CARNAL BUTCHERY. Soon the release of SEVERE CARNAL BUTCHERY helped Sepsism become well known all over the world. SEVERE CARNAL BUTCHERY became an instant cult classic. SEPSISM began touring and opening shows for many of Deathmetal's elite.
