Helmet is an American alternative metal band formed in 1989 in New York City by vocalist and guitarist Page Hamilton. Known for their heavy, precise guitar riffs and unconventional song structures, Helmet helped shape the sound of 1990s post-hardcore and alternative metal. Their music blends elements of metal, punk, and noise rock, often featuring stop-start rhythms and dissonant chords. The band gained critical acclaim and a strong underground following, influencing many artists in the heavy music scene. Despite lineup changes over the years, Helmet remains active, with Hamilton as the consistent driving force.
