Ratt

RATT burst out of the Los Angeles metal scene in the late 1970s, evolving from the San Diego-origin group Mickey Ratt into a polished, radio-ready hard rock powerhouse. Frontman Stephen Pearcy joined as they refined twin guitar harmonies and punchy rhythm parts, teaming with Robbin Crosby and Warren DeMartini on guitars, Juan Croucier on bass, and Bobby Blotzer on drums. Their early energy fused street-smart hooks with stadium-sized riffs, setting the template for American glam metal and live high-energy performances.

In the mid-80s, Out of the Cellar (1984) propelled RATT into the mainstream, aided by the MTV era and hits like Round and Round. Invasion of Your Privacy (1985) built on that momentum with more combustible riffs and chorus-driven anthems. The band became one of the era's defining acts, known for their dual guitar harmonies, tight rhythm sections, and flamboyant style. Over the years, they have experienced lineup changes and hiatuses, but Pearcy's vocal presence and their signature sound endured, influencing countless hard rock and metal players and leaving a lasting imprint on the glam metal landscape.
