Keith Deen, former vocalist of 1980s Los Angeles thrashers HOLY TERROR, died on Thursday, December 13 after a three-month battle with cancer. He was 56 years old.

HOLY TERROR was formed in the mid-1980s by Kurt Colfelt (a.k.a. Kurt Kilfelt; ex-AGENT STEEL) and ex-DARK ANGEL drummer Jack Schwarz, who left before the release of the band's first album, 1987's 'Terror And Submission'.

A follow-up effort, 'Mind Wars', was issued in 1988.

Stated Colfelt:

"With the loss of Keith Deen, a part of me is gone as well."

After resurrecting HOLY TERROR in 2005, Colfelt revealed that he "attempted to get in touch" with Deen about having him front the band again but that Keith's non-response was a clear signal that the singer was not interested in taking part in the group's reunion.

A HOLY TERROR DualDisc release, 'El Revengo', came out in 2006 through the U.K.-based label Blackend Records.
