Exhorder is an American metal band from New Orleans, Louisiana. They are credited as the purveyors of the groove-oriented thrash sound later made famous by bands such as Pantera, White Zombie, and Machine Head. Their debut LP was regarded as a large influence on the NOLA metal scene Initially active from 1985 to 1994, they have since reformed in 2008.
Exhorder was formed in 1985 in New Orleans, Louisiana. After releasing several demos in the vein of pure thrash metal, they started to adapt more of a groove metal-oriented sound with their debut studio album, Slaughter in the Vatican, released in 1990. This sound was further developed by their second (and to date last) album, The Law, released in 1992. The band dissolved two years later.
