metalcore tends to have somewhat indecipherable lyrics and awesome, though distorted, instrumentals featuring the guitar. Metalcore tends to be nfluenced by various themes including, at times, the strait edge, anti-drug/sex them.
lamb of god, unearth and other groups are considered metalcore.

Metalcore is a genre that has been around since the eighties but not totally popularized until the mid 90's with bands such as Unearth, the modern forerunners in the genre. It includes a mixture of hardcore punk and heavy metal and uses generally two guitarists, a bassist and double kick drums for the instrumentals. Many bands use more than one singer, one generally for more melodic lines and the other, lead singer, who carries many of the vocal burden and usually "screams".
Metalcore bands include: 36 Crazyfists, As I Lay Dying, Bleeding Through, Bloodsimple, Diecast, God Forbid, Haste The Day, Hatebreed, Lamb of God, Norma Jean, Still Remains, Unearth, Walls of Jericho.

A genre of music that had began in the late 80s/early 90s. Originally combining elements of metal and hardcore, it has now evolved into a dime-a-dozen plethora of bands that sound exactly the same. New school metalcore bands borrow heavily from melodic European death metal combined with stolen Slayer riffs and vocals ranging from annoying screams to cupped-mike growls. Band names are usually longer than the songtitles (i.e. Between The Buried And Me, Every Time I Die, etc). Mostly caters to mallrat teens who are glued to Facebook, shop at Hot Topic, wear skinny jeans, skateboard, and play Call Of Duty all day long.
Old school metalcore: Insult II Injury, Merauder, Into Another

New school metalcore: Bullet For My Valentine, As I Lay Dying, All That Remains

A genre of new age metal that began in the late 1990's with bands like Slipknot and Killswitch Engaged. It infuses Punk and Extreme Metal to create a strong, yet complex rhythm. It differs from Punk Metal by putting emphasis on the breakdown portion of the song, and often invoke a more depressed and somewhat hopeless feeling. Some other modern examples include Attack Attack, Underoath, Atreyu, Trivium, All That Remains, and many more.

A subgenre of metal and hardcore that is kind of like communism. If it were to be done correctly, it would be perfect, but hardly anyone can do it right and therefore it is mainly horrible. There are some metalcore bands that I actually enjoy (The Dillinger Escape Plan, Hatebreed, Every Time I Die), but most of it (and certainly the most popular bands) incorporate pop punk, electronic, glam, crunk, and all sorts of other shit and make it sound worse than putting a cat in a blender. Not to mention deathcore, which is just an attempt to make an anti-metalcore genre, is even worse and brings shame to death metal. Another thing that humor's me with most metalcore is the bands claim to be the brutalist shit alive but they dress like a 12 year old scene girl.
Good metalcore: Every Time I Die, TDEP, Hatebreed, All That Remains (sort of), ect.
Bad metalcore: Bring me the Horizon, Of Mice and Men, Asking Alexandria, The Black Dahlia Murder, Chelsea Grin, ect.

A subgerne of metal and hardcore that is NOT shit, but is often called shit because a lot of bands don't work to their full potential, and because there are too many bands that are called metalcore and are actually NOT! Real metalcore is usually 70-90% metal and 10-30% hardcore. Fake metalcore is really post hardcore in is often called so because of the existence of a breakdown and screamed vocals! Real metalcore also has guitar solos now and then and often use a low toned type of screaming. Fake metalcore absolutely has no solos and consistently use both screams and death growls, as well as a lot of singing! So next time you here of a metalcore band, compare them to bands like As I Lay Dying, August Burns Red, All That Remains, Killswitch Engaged, etc... If they sound like them, it's real metalcore, if they don't, it's not!

Real Metalcore bands: Underoath (Only there first 2 albums) All That Remains, Avenged Sevenfold (Only there first 2 albums), As I Lay Dying, August Burns Red, Killswitch Engaged.

Fake Metalcore Bands: Underoath (Everything else they made after Cries of The Past), Motionless in White, Attack Attack!, Asking Alexandria
Metalcore hater: I think metalcore sucks!
Me: Why?
Metalcore haiter: Beacuse metalcore bands like Asking Alexandria sounds like emos trying to play metal!
Me: (facepalms) Asking Alexandria is NOT metalcore!
Metalcore haiter: Yes they are, it says so on Wikipedia.
Me: (Facepalms again) No they aren't, they are only called so because they have breakdowns in there songs and have screamed vocals. Listen to August Burns Red for an example of what REAL metalcore is!
(All of August Burns Red's discography and some of All That Remains songs later)
Metalcore lover (Formally a metalcore haiter): August Burns Red is the BEST BAND EVER!
