Testament (American thrash metal band)

Formation and early years

The band began in Berkeley, California, in 1983, a fertile environment for heavy music at the time. Early on they recorded demos and toured regionally, and they changed their name from an earlier moniker to avoid conflicts and to better reflect their developing style. Their late-1980s records established them as a force in the international metal community. For context about their place of origin, see more on Berkeley.

Musical style and themes

Testament's sound mixes the speed and ferocity of thrash with melodic phrasing and technically demanding guitar work. Songs often feature rapid palm-muted riffs, harmonic leads, complex solos and dynamic shifts. Lyrical subjects span social and political issues, personal struggle, darker spiritual topics and fiction; the band has alternated between straightforward thrash intensity and more experimental or groove-oriented approaches at different points in their career.
