with protopunk bands such as The Stooges, and have appeared at punk, metal, and rock concerts. Ska punk promoted an updated version of skanking. Hardcore dancing is a later development influenced by all of the above-mentioned styles. Psychobillies prefer to "wreck", a form of slam dancing that involves people punching each other in the chest and arms as they move around the circle pit. Literature Punk has generated a considerable amount of poetry and prose. Punk has its own underground press in the form of punk zines, which feature news, gossip, cultural criticism, and interviews. Some zines take the form of perzines. Important punk zines include Maximum RocknRoll, Punk Planet, No Cure, Cometbus, Flipside, and Search & Destroy. Several novels, biographies, autobiographies, and comic books have been written about punk. Love and Rockets is a comic with a plot involving the Los Angeles punk scene.

The Medway Poets performance group included punk musician Billy Childish and had an influence on Tracey Emin. Jim Carroll's autobiographical works are among the first known examples of punk literature. The punk subculture has inspired the cyberpunk and steampunk literature genres, and has
