Founded with John Bush (vocals), Phil E. Sandoval (guitar), Dave Prichard (guitar), Joey Vera (bass) and Gonzo Sandoval (drums), they signed to 'Chrysalis' on the strength of their inclusion on the Metal Massacre II compilation.
Their debut, March Of The Saint EP (1984), soon followed; the album featured what was best described as "proto-Thrash", a primitive Thrash Metal sound that was quickly followed-up with two equally influential albums, Delirious Nomad (1985) and Rising Fear (1987). These albums received more interest from fans. They also featured better production and a more dynamic Thrash sound. Sundoval, however, had split during the recording of the latter to form Megattack.
They continued as a four piece until Jeff Duncan (ex-Odin) was recruited. Both albums hovered just over the U.S. 100 marker when their label suddenly dropped them claiming sales were insufficient to renew their contract. Many critics, however, believed the sales were low because the label didn't know how to promote them properly. They signed to 'Enigma/Metal Blade' shortly later and released a live act, Saints Will Conquer - Live (1988). It would be three years before a new studio effort came in the form of Symbol Of Salvation (1991). The album proved to be their most acclaimed piece but the celebration would be short, with Bush leaving to Anthrax. The album was also launched without Prichard due to his death from Leukemia the year previous. Alan Barlam replaced Duncan. The band split shortly after.
In late 1998 Armored Saint announced they would return with most members back to try again and the resulting Revelation (2000). The 2-CD compilation best of featuring their early demos and some new stuff, Nod To The Old School, popped out in early 2001 under the line-up John Bush (vocals), Jeff Duncan (guitar), Phil Sandoval (guitar), Joey Vera (of Fates Warning/ex-Engine; bass), Gonzo Sandoval (drums), many of whom continued in their new outfits while employed in Armored Saint.
