Social Distortion (often known as Social D) are an American punk rock band, formed in 1978 in Fullerton, Orange County, California by frontman Mike Ness. They are, along with many others, often credited as one of the leading bands of the 1980s punk revival. The band has remained silent three times and once broke up in 1985, due to seperate interests. However, they reformed around 1987 and have continued being active today, especially after longtime guitarist Dennis Danell passed away from an apparent brain aneurysm in 2000.
