The Cramps were an American punk band, formed in 1976 and active until 2009 with the death of lead singer Lux Interior. Their line-up rotated much over their existence, with the husband and wife duo of Interior and lead guitarist Poison Ivy the only permanent members. Guitarist Bryan Gregory and drummer Pam Ballam rounded out the first complete lineup in April 1976. They were part of the early CBGB punk movement that had emerged in New York. By being the first known band to blend punk rock with rockabilly, The Cramps are widely recognized as innovators of psychobilly.
