Originating from San Francisco’s Bay Area, Testament was formed in 1983 under the name Legacy before adopting its definitive moniker just prior to the release of their debut album. Led by guitarist Eric Peterson and charismatic frontman Chuck Billy, the band quickly rose to prominence as one of the leading forces in American thrash metal, alongside Metallica, Slayer, Megadeth and Anthrax.

Their debut record The Legacy (1987) laid the groundwork for a sound that was both technical and ferocious, followed by cornerstone albums like Practice What You Preach (1989) and Souls of Black (1990). Guitarist Alex Skolnick’s virtuosity and Chuck Billy’s powerful vocals quickly became defining elements of the band’s identity.

Remaining true to their thrash roots while exploring death and groove metal influences, Testament have continued to evolve without ever losing their edge. Later works such as The Formation of Damnation (2008) and Titans of Creation (2020) reaffirmed their status as one of the most enduring and respected acts in the metal world.
