A variety of punk rock originating in the US in the early '80s. It involves shouted vocals (as opposed to growled) with a fast, aggressive tempo and a guitar sound featuring quick chord changes. Minor Threat, Bad Brains, SSD, and the Circle Jerks are known for this style. By 1986, a new style of hardcore came out of the New York scene. The NYHC scene added mosh breakdowns to mix, but the music retained its fast aggressive nature. This spawned the youth crew scene, a positive straight edge scene featuring such bands as Youth of Today, Chain of Strength, and the Gorilla Biscuits. Judge is a notable band from this era that added some metal style to their riffs. In the 90s hardcore took many different direction, bands like Lifetime and Turning Point took the late '80s sound (particularly the melodic approach pioneered by the Gorilla Biscuits) and added a softer sung vocals and the lyrical approach of DC bands like the Rites of Spring and Dag Nasty. Other bands like Earth Crisis mixed hardcore with death metal growls and slow brutal guitars. Today many bands continue to play the early '80s fast, thrashy style as well as the so-called '88 or youth crew style, while still others have taken the sound of bands like Earth Crisis farther and mixed in more metal elements such as double bass drumming. Hardcore refers to all of these styles, though metalcore is best used to identify bands like Throwdown or Converge (who don't really sound anything alike but both mix metal and hardcore). Finally, some bands like Bane, With Honor, and Comeback Kid are mixing positive youth crew style hardcore with more complex metal riffing without straying into the beatdown, double bass drumming style of metalcore. People talking about old-school hardcore should be referring to one of the hardcore sounds that developed in the '80s, regardless of when the band formed.

definitions of hardcore music are widely different, so this definition is meant as a guide. hardcore did originally grow out of punk somwhere along the line in the 80's. and when i say punk, i mean punk in the ballpark of the Misfits. it began to stand on its own in the early 90's with a few pioneering bands. these early bands were very unpolished, but people looking for the heaviest sound possible became the first fans. throughout the 90's, the line between hardcore and metal thinned, because at the same time some metal bands were also finding a heavier sound.
now skip ahead to the present. at this point, that heavy metal/90's hardcore gap has been closed. however there is a new barrier. everything changed when bands like Terror, Hoods, and Madball started hitting the scene (for lack of a better word). there is no denying the difference between Terror and Unearth. now that awful term "metalcore" has come about. Unearth leans sounds sort of hardcore, but they are metal. Terror is 'straight up' hardcore. kids who listen to Terror know that what they listen to is heavier than what Unearth kids listen to. so as far as they're concerned, Unearth IS NOT hardcore. so now there is 'hardcore' and there is 'real hardcore' or 'straight up hardcore'. THERE IS A DEFINATE DIFFERENCE BETWEEN THE TWO STYLES OF MUSIC.
most fans of 'straight up hardcore' accept and like 'hardcore' music, but dont like it being called hardcore. and they dont like 'hardcore' kids trying to act tough, because they know the music they listen to is tougher. so as much as i am against terms like "metalcore" it is probably a good idea to start using them because of the difference between the metal side and hardcore side.
there is no 'hardcorest' music, just hardcore. if something more hardcore comes along, then that becomes the definition of hardcore. thats why bands like Terror are taking the term for themselves with little opposition; because they are right to. when critics hail their album saying "this is what hardcore is supposed to sound like" there is little arguing that its for real.
Zao (most metal side of what is called hardcore)
Unearth (a blend of hardcore and metal that leans very much on the metal side)
Remembering Never (a blend of hardcore and metal that leans very much on the hardcore side)
Terror (doesnt get more hardcore than this)

Hardcore is not a specific type of music, or certain style of clothing. Hardcore is a room filled with people who just like you got picked on in school and in life, and in wanting something more than the monontony that is life.

...and it's not about dancing. but dancing jumping kicking screaming and moshing (even push moshing and circle pits) are fun
Hardcore = living your life, your real life
Not Hardcore = having to look up what it means to be hardcore on the internet.
Myspace = not real life.
Going to a protest, rally, or sit in = real life
get off your myspace and go change the world.

If punk rock is frustrated, then this is pissed off. that is one way i can describe it. a key thing to remember is that Hardcore is Punk, but Punk is not always Hardcore. if you think hardcore is As i Lay Dying you are confused. switch that band out for some Tragedy and you are all set.

if what you call hardcore has a solo more than 7 seconds than it is not hardcore. not all hardcore has breakdowns but a lot does. if what you call hardcore has no cussing it probably is not hardcore unless it is American Nightmare.
Converge = Not Hardcore
Modern Life is War = Hardcore
He is Legend = Not Hardcore
Outbreak = Hardcore

waking up hungover and cracking open a beer, drinking nonstop from noon to 4am, busting in on a smush and filming it, owning every party in town, winning every game of flip cup

Hardcore is more than music. Its a way of life for some many people. Not just from the begining of punk rock since the beginning of rock and roll in general people who listen to hardcore live a different lifestyle, dress a different way, listen to louder music than the average person does.
Goofus listens to pop punk hes not hardcore at all.
Gallant listens so hardcore/metal and dresses different hes so freaking hardcore.

Usually used to describe someone who punches their fist in the air and say that they're hardcore and punk and against anything conformist. This is rather interesting because you must conform to their clothes and music and depressiveness before they will let you hang out with them.
"Did you go to that concert last night? we were so hardcore."
"O my god did you see Ben, he is so not hardcore."
