Circle of Vengeance

During the time that they were playing pure thrash metal in the style that the Bay Area bands had carved out for themselves in the '80s/early '90s, C.O.V. recorded a 30-minute demo in 1991 (engineered by Masaki Liu and known as the "Masaki Demo"), which was used to audition vocalists. The lineup on it is Brian Regan (guitars), Scott Anderson (guitars), Jack Gibson (bass), and Mike Bennett (drums). While never officially released, it has circulated heavily in the underground and showcases their early sound before transitioning into a more groove-oriented metal band and releasing a 2-song demo tape in 1995 (which was later included on the 2004 "Nerve Damage" compilation by Skinlab , a band that featured later-period C.O.V. vocalist Steev Esequivel).
