Until about 1983, hardcore was used fairly sparingly, and mainly
as a descriptive term. (i.e., a band would be called a "hardcore
band" and a concert would be a "hardcore show").
American teenagers who were fans of hardcore punk simply considered
themselves fans of punk — although they were not necessarily
interested in the original punk rock sound of late 1970s (i.e.
the Sex Pistols, the Ramoness, Johnny Thunders and the Heartbreakers).
In many circles, hardcore was an in-group term, meaning 'music
by people like us,' and it included a wide range of sounds, from
hyper-speed punk rock to sludgy dirge-rock, and often including
arty experimental bands, such as The Stickmen and Flipper.
Hardcore was noted for its do-it-yourself (DIY) approach. In most
cities (California being the exception) the hardcore scene relied
entirely on DIY recordings, zines, radio shows and concerts. Hardcore
punk fans brought a dressed-down T-shirt, jeans, and crewcut style
to punk fashion. This contrasted with the more elaborate and provocative
clothing styles of many 1970s punk rockers, such as Richard Hell,
Sid Vicious and Soo Catwoman.
