Don't know how this band avoided my attention back in the 80's, but....
Vio-Lence was a thrash metal band being part of the legendary Bay Area Thrash scene. Formed in 1985 as Death Penalty and shortly after changed the name to Vio-Lence.
They released three full-lengths, before they split up in the mid 90's.
Discography:
Eternal Nightmare (1988)
Oppressing the Masses (1990)
Nothing To Gain (1993)
This is old-school thrash metal as its best and Eternal Nightmare will be up on the frog shortly...
