Discharge

Discharge are an English hardcore punk band formed in 1977 in Stoke-on-Trent, England. The band is known for influencing several sub-genres of extreme music and their songs have been covered by some of the biggest names in heavy metal and other genres. The musical sub-genre of D-beat is named after Discharge and the band's distinctive drumbeat.

The band is characterized by a minimalistic approach to music and lyrics, using a heavy, distorted and grinding guitar-driven sound and raw, shouted vocals similar to a political speech, with lyrics on anarchist and pacifist themes, over intense drone-like rhythms. The band's sound has been called a "grave-black aural acid assault." 

Discharge "paved the way for an astounding array of politically motivated, musically intense and deeply confrontational bands". Discharge was "explicitly political" and used a "revolutionary/activist" attitude that moved hardcore away from its pub rock origins and towards a "dangerous and provocative" territory.

Discharge's influence on heavy metal is incalculable and metal superstars such as Metallica, Anthrax, Machine Head, Sepultura, Soulfly, Prong and Arch Enemy have covered Discharge's songs in tribute.
