Formerly called Evil, they changed their name to Sabbat in 1984.
Samm and Gezol are brothers.

Gezol founded Evil Records and released the early Sabbat recordings on this imprint.

In September '87, Sabbat played a farewell live show (they stopped playing live due to a death in Gezol and Samm's family), later on released as the "Live Curse" album. The band continued recording new studio material. In 1990 Gezol decided to return to performing live.
