John Duncan, known professionally as Big John Duncan, is best known as the guitarist for The Exploited from their classic lineup of 1980–83.[1] During that time he played on the albums Punk's Not Dead and Troops Of Tomorrow. He also played on many of their single releases, the most famous being "Dead Cities", which led to them playing on Top Of The Pops.
After quitting the band in 1983, Duncan went on to play in several other bands including The Square Peg and The Blood Uncles, and joined Goodbye Mr. Mackenzie (with future Garbage singer Shirley Manson), as well as being a guitarist in some concerts of Nirvana in 1993 and being a technician for the band.[1]
