Defiance is an American thrash metal band known for its aggressive sound and politically charged lyrics. The band formed in the late 1980s in the Bay Area thrash scene, which was home to many influential metal bands of the time. Defiance established their presence with a blistering brand of thrash that was both technically proficient and brimming with raw energy, earning them a reputation as a formidable force within the metal community.

Through the years, Defiance went through several lineup changes and hiatuses but has maintained a consistent output of material which resonates with their core fanbase. Their recent works, including tracks like "Drift," "Last of a Dyin Breed," and "Arcanum Phases," display a matured sound that has evolved without losing the intensity that originally put them on the map. "Mirror" and "Game Over!" encapsulate their signature blend of fierce riffs and socially aware messages. Staying true to their roots, the self-titled release "Defiance" and the collection "A Decade of Defiance 1993 - 2003" serve as testaments to their enduring legacy in the metal scene. "Rise or Fall" continues to showcase their dedication to creating music with a punch, further cementing their status as thrash metal stalwarts.
