Psychobilly (also known as punkabilly) is a rock music fusion genre that fuses elements of rockabilly and punk rock. It has been defined as "loud frantic rockabilly music", it has also been said that it "takes the traditional countrified rock style known as rockabilly, ramp[ing] up its speed to a sweaty pace, and combin[ing] it with punk rock and imagery lifted from horror films and late-night sci-fi schlock,... [creating a] gritty honky tonk punk rock."

A rivethead or rivet head is a person associated with the industrial dance music scene. In stark contrast to the original industrial culture, whose performers and heterogeneous audience were sometimes referred to as "industrialists", the rivethead scene is a coherent youth culture closely linked to a discernible fashion style. The scene emerged in the late 1980s on the basis of electro-industrial, EBM, and industrial rock music. The associated dress style draws on military fashion and punk aesthetics with hints of fetish wear, mainly inspired by the scene's musical protagonists.

Noisecore is a fusion genre that merges hardcore punk and noise rock. Originally emerging in the mid-1980s, the genre is characterized by chaotic song structures, short track lengths, unintelligible lyrics, heavy guitar feedback and distortion, blast beats, noise-laden soundscapes, as well as a rejection of musical theory.
