DISCHARGE is a British hardcore punk band formed in 1977, often considered among one of the very first bands to play hardcore punk. While the band had substantial lineup changes over its history, the core members over the early 1980s, when the band produced its key recordings, were Kelvin "Cal" Morris (vocals), Tony "Bones" Roberts (guitar), Roy Wainwright (bass), and Terry Roberts (drums).
The band's music is characterized by a heavy, distorted, and grinding guitar-driven sound and rawly shouted vocals, with lyrics on anarchist and pacifist themes. The band's first album in 1982, Hear Nothing See Nothing Say Nothing, was an instant classic defining the so called d-beat genre.
In the early 1980s, the group did a number of singles and EPs like the famous 1981 EP Why or the 1982 single State Violence State Control.
After 1982, the addition of guitarist Peter "Pooch" Purtill brought significant thrash metal crossover elements to the band. In the 1990s, the band released several metal-influenced albums, which alienated some of the original fan base. In the early 2000s, the original line up was reunited and they released a self-titled album using the 1980s musical style. DISCHARGE's music influenced hardcore punk, thrash metal, crust punk, grindcore and various extreme metal subgenres.
