Discharge

Discharge is a British hardcore punk band formed in 1977 by Terry "Tezz" Roberts and Roy "Rainy" Wainwright. They are often considered among one of the very first bands to play hardcore punk, and mixing punk with metal. 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).
