One of the best genres of metal there is in my opinion. Originated in the late 80's. Cross between hardcore metal and hardcore punk. A lot better than shitty nu-metal.
Metalcore bands include the OLD avenged sevenfold, OLD atreyu, underoath, lamb of god, killswitch engage, bullet for my valentine, as i lay dying, some black dahlia murder, all that remains, some machine head are some of the more mainstream stuff. a good unknown band is august burns red.

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

Metalcore is a mix of heavy metal and hardcore music. It originated in the 1980's with bands like Integrity. Metalcore used to be refered to as Cross-Over Thrash, as stated by bands such as Dirty Rotten Imbecilesand Nuclear Assault.

Today, Metalcore and Cross-Over Thrash are considered two completely different genres of music. Nuclear Assault was among the first bands to call themselves Heavy Metal/Hardcore Punk band. Breakdown was arguably one of the earliest to fuse heavy metal-influenced riffing with a more traditional hardcore sound without being a thrash metal band.

Breakdowns are essential part of metalcore. Typically, the guitars play a set of rhythmically oriented riffs, usually on open strings so as to achieve the lowest sound the guitars are tuned for. These riffs are often accented by the drummer with double kick bass drums.
Examples of metalcore are: theBLED, Haste The Day, Bleeding Through, Underoath (Act Of Depression & Cries Of The Past), Killswitch Engage, As I Lay Dying, The Black Dahlia Murder, Bury Your Dead, Norma Jean, The Chariot, Darkest Hour, The Dillinger Escape Plan, Between The Buried And Me, Escape The Fate, Every Time I Die, Evergreen Terrace, Hatebreed, The Haunted, Misery Signals, The Number Twelve Looks Like You, Parkway Drive, Unearth, Vanna, and Walls Of Jericho.

The latest trend in metal music... if you want to call it that. Metalcore is a genre crossbreed of heavy metal and hardcore that claims to be better than its nu-metal predecessors, which in some ways is true. However, metalcore is bad in it's own right. For example, every metalcore band sounds exactly the same, and god forbid the lead singers actually try to "sing" for once instead of the usual incoherent bad screaming. Metalcore is also unappealing and unlistenable to all but a small audience of devoted fans, as the songs lack any real hooks which keeps it from getting too mainstream, a double-edged sword. Metalcore has its ups, however; most metalcore bands are at least twice as talented as their nu-metal counterparts (instrumentally) and lacks the annoying rap aspect of said music. Heavy Metal fans should own at least one decent metalcore CD from bands like "Down the Sun" or "Sinai Beach", if only for the sake of being obnoxious and blasting it in your car with the windows down.
