Psychobilly (also cowpunk, a somewhat earlier name) is a term used to describe bands who play a genre of music heavily based in punk rock, but with many elements of rockabilly. In addition, modern psychobilly often resembles horror punk[?]. Musicians of this genre are often associated with a hairstyle called a quiff[?], which resembles a mohawk. The Misfits' "American Nightmare" may have been the first psychobilly song. Perhaps the most popular psychobilly artist is the Rev. Horton Heat[?].
