merging from the original Thrash scene, Dark Angel, featuring the original line-up of Don Doty (vocals), Jim Durkin (guitar), Eric Meyer (guitar), Ron Yahn (bass) and Jack Schwartz (drums) would release two albums in the mid 1980s, We Have Arrived (1984) and Merciless Death (1985) before signing to Combat' around the same time they replaced their rhythm section of Yahn and Schwartz with Mike Gonzales and Gene Hoglan respectively for the 1986 release of Darkness Descends to become a classic in the Thrash Metal sub-genre featuring nasty vocals themes and bulldozer riffing.
Leave Scars (1989) saw new vocalist Ron Rineheart in place. By this time the act had earned the mottos, the L.A. Caffeine Machine", and, "too fast, my ass" for their high-speed style. The album featured a brutal cover of Led Zeppelin's Immigrant Song. Although no less compromising than its predecessor it surprisingly made U.S. top 200. Their only live effort, Live Scars, came in 1989. But their final set came in 1991 with Time Does Not Heal with Brett Eriksen replacing Durkin before they shut the show down when Hoglan joined Death Metal pioneers Death.
