Sheer Terror was an influential and long-lasting American hardcore band from New York City. The band was one of the first to mix shades of heavy metal with a hardcore punk base, pioneering a heavier style of hardcore that would become popular in the following decades. Formed in late 1984, the band, for the most part, stayed together until 1998, surviving numerous lineup changes and shifts in musical style. In October of 2004, the band reunited and gave two final farewell shows at New York's legendary CBGB Club.
