What was the year the original band featuring the bassist from Act of Defiance was formed?
Act of Defiance Act of Defiance is an American extreme metal supergroup from Los Angeles, California, formed in 2014 by guitarist Chris Broderick and drummer Shawn Drover of Megadeth after they both resigned from the band on the same day, vocalist Henry Derek (ex-Scar the Martyr frontman) and bassist Matt Bachand (Shadows Fall guitarist).
Allegiance (Australian band) Allegiance were an Australian thrash metal group. They formed in 1990 in Perth and disbanded in 1997. They released two studio albums, "D.e.s.t.i.t.u.t.i.o.n" (1994) and "Skinman" (1996). According to Australian musicologist, Ian McFarlane, they "gained international acclaim and interest from several key figures in the heavy metal world. [Their] tight sound mixed the heavy riffs and complexities of San Francisco Bay Area thrash bands like Metallica, Testament, Slayer and Exodus with a touch of Sepultura."
