C.I.A.

A. (standing for 'Corporation In Action') was a speed metal and crossover project formed by Glenn Evans, best known as the drummer for thrash legends Nuclear Assault.

Emerging in the late 1980s and early 1990s, the band served as a creative outlet for Evans to explore a more direct, punk-influenced sound while handling multiple instrumental duties. Their debut, 'In the Red' (1990), and the follow-up, 'Attitude' (1992), are quintessential examples of the crossover subgenre, blending the technical precision of thrash with the raw, socio-political aggression of hardcore punk. Critically, the band is viewed as a cult favorite within the thrash community, often noted for its high-energy performances and Evans' distinctive rhythmic sensibility. While they never achieved the mainstream success of Nuclear Assault, their work remains a significant artifact of the era when the boundaries between the metal and punk scenes were most porous.
