History
First wave (1985-1994)
In 1985 in Washington, D.C., Ian MacKaye and Guy Picciotto,
veterans of the DC hardcore music scene, decided to shift
away from what they saw as the constraints of the basic
style of hardcore and the escalating violence within the scene.
They took their music in a more personal direction with a far
greater sense of experimentation, bringing forth MacKaye's
Embrace and Picciotto's Rites of Spring. The style of music
developed by Embrace and Rites of Spring soon became its own sound.
(Hüsker Dü's 1984 album Zen Arcade is often cited as a major
influence for the new sound.). As a result of the renewed spirit
of experimentation and musical innovation that developed the new
scene, the summer of 1985 soon came to be known in the scene as
"Revolution Summer".

Where the term emo actually originated is uncertain,
but members of Rites of Spring mentioned in a 1985
interview in Flipside Magazine that some of their
fans had started using the term to describe their music.
By the early 90s, it was not uncommon for the early DC
scene to be referred to as emo-core, though it's unclear
when the term shifted.

Within a short time, the D.C. emo sound began to influence
other bands such as Moss Icon, Nation of Ulysses, Dag Nasty,
Soulside, Shudder to Think, Fire Party, Marginal Man,
and Gray Matter, many of which were released on MacKaye's
Dischord Records. The original wave of DC emo finally ended
in late 1994 with the collapse of Hoover.

As the D.C. scene expanded, other scenes began to develop
with a similar sound and DIY ethic. In San Diego in the
early 1990s, Gravity Records released a number of records
in the hardcore emo style. Bands of the period included Heroin,
Indian Summer, Angel Hair, Antioch Arrow, Universal Order of
Armageddon, Swing Kids, and Mohinder. Also in California,
Ebullition Records released records by bands of the same vein,
such as Still Life and Portraits of Past, as well as more
traditional hardcore punk bands, all having various social
and political themes in common.

At the same time, in the New York/New Jersey area,
bands such as Native Nod, Merel, 1.6 Band, Policy of 3,
Rye Coalition, Iconoclast and Quicksand were feeling
the same impulse. Many of these bands were involved with
the ABC No Rio club scene in New York, itself a response
to the violence and stagnation in the scene and with the
bands that played at CBGBs, the only other small venue for
hardcore in New York at the time. Much of this wave of emo,
particularly the San Diego scene, began to shift towards
a more chaotic and aggressive form of emo, nicknamed screamo.

By and large, the more hardcore style of emo began to fade
as many of the early era groups disbanded. However,
aspects of the sound remained in bands such as Four Hundred
Years and Yaphet Kotto. Also, a handful of modern bands
continue to reflect emo's hardcore origins, including Circle
Takes the Square, Hot Cross, City of Caterpillar,
Funeral Diner, and A Day in Black and White.

Following the disbanding of Embrace in 1986, MacKaye
established the influential group Fugazi, and was soon
joined by Picciotto. While Fugazi itself is not typically
categorized as emo, the band's music is cited as an
influence by popular second-wave bands such as Sunny Day
Real Estate, Braid, and Jimmy Eat World.


Early influence
In California - particularly in the Bay Area - bands such
as Jawbreaker and Samiam began to incorporate influences
from the "D.C. sound" into a poppier framework; The former's
music was described by Andy Greenwald as "a sonic shot-gun
marriage between the bristly heft of hardcore, the
song-writing sensibility of Cali pop-punk, and the
tortured artistry of D.C. emo". Other bands soon
reflected the same sense of rough melody, including Still
Life and Long Island's Garden Variety.

Also in the early 90s, bands like Lifetime reacted in their
own way to the demise of youth crew styled straight-edge
hardcore and desired to seek out a new direction. While
their music was often classified as emo, it was also considered
to be melodic hardcore. In response to the more metal direction
their hardcore peers were taking, Lifetime initially decided to
slow down and soften their music, adding more personal lyrics.
The band later added a blend of speed, aggression, and melody
that defined their sound. Lifetime's sound, lyrics, and style
were a virtual blueprint for later bands, including Saves the Day,
Taking Back Sunday, and The Movielife.


Second wave (1994–2000)
As Fugazi and the Dischord Records scene became more and more
popular in the indie underground of the early 1990s, new bands
began to spring up. Combining Fugazi with the post-punk influences
of Mission of Burma and Hüsker Dü, a new genre of emo emerged.

Perhaps the key moment was the release of the album Diary by
Sunny Day Real Estate in 1994. Given Sub Pop's then-recent
success with Nirvana and Soundgarden, the label was able to
bring much wider attention to the release than the typical
indie release, including major advertisements in Rolling Stone.
The heavier label support allowed the band to secure performances
on TV shows, including The Jon Stewart Show. As a result, the
album received widespread national attention.

As more and more people learned about the band, particularly
via the fledgling World Wide Web, the band was given the tag emo.
Even where Fugazi had not been considered emo, the new generation
of fans shifted the tag from the earlier hardcore style to this
more indie rock style of emo. It was not uncommon for Sunny Day
and its peers to be labeled with the full "emo-core". However,
when pressed to explain "emo", many fans split the genre into
two brands: the "hardcore emo" practiced in the early days and
the newer "indie emo".

In the years that followed, several major regions of "indie emo"
emerged. The most significant appeared in the Midwest in the mid-90s.
Many of the bands were influenced by the same sources, but with
an even more tempered sound. This brand of emo was often referred
to as "Midwestern emo" given the geographic location of the bands,
with several of the best-known bands hailing from the areas around
Chicago, Kansas City, Omaha and Milwaukee. The initial bands in
this category included Boy's Life and Cap'n Jazz. In ensuing years,
bands such as The Promise Ring, Braid, Elliott, Cursive, and
The Get Up Kids emerged from the same scene and gained national attention.

The area around Phoenix, Arizona became another major scene for emo.
Inspired by Fugazi and Sunny Day Real Estate, former punk rockers
Jimmy Eat World began stirring emo influences into their music,
eventually releasing the album Static Prevails in 1996.
The album was arguably the first emo record released by a major label,
as the band had signed with Capitol Records in 1995.

Other bands that followed the "indie emo" model included Colorado's
Christie Front Drive, New York's Texas Is the Reason and Rainer Maria,
California's Knapsack and Sense Field, Baltimore's Cross My Heart,
Austin's Mineral, and Boston's Piebald and Jejune.

As "indie emo" became more widespread, a number of acts who otherwise
would not have been considered part of the "indie emo" scene began to
be referred to as emo because of their similarity to the sound.
The hallmark example was Weezer's 1996 album Pinkerton, which, years later,
was considered one of the defining "emo" records of the 90s.

As the wide range of emo bands began to attract notoriety on a national scale,
a number of indie labels attempted to document the scene. Many emo bands of
the late 90s signed to indie labels including Jade Tree Records,
Saddle Creek Records, and Big Wheel Recreation. In 1997, California's Crank!
Records released a compilation titled (Don't Forget to) Breathe,
which featured tracks by notable indie emo bands such as The Promise Ring,
Christie Front Drive, Mineral, Knapsack, and Arizona's Seven Storey Mountain.
In 1998, Deep Elm Records released the first installment in a series of
compilations called Emo Diaries, featuring tracks from Jimmy Eat World,
Samiam, and Jejune. In 1999, famed 70s compilation label K-tel released
an emo compilation titled Nowcore: The Punk Rock Evolution,
which included tracks by Texas Is the Reason, Mineral, The Promise Ring,
Knapsack, Braid and At the Drive-In among others.

With the late-90s emo scene being more national than regional, major
labels began to turn their attention toward signing emo bands with
the hopes of capitalizing on the genre's popularity. Many bands resisted
the lure, citing their loyalty to the independent mentality of the scene.
Several bands cited what they saw as mistreatment of bands such as Jawbox
and Jawbreaker while they were signed to majors as a reason to stay away.
The conflict felt within many of the courted emo bands resulted in their
break-ups, including Texas Is the Reason and Mineral.

By the end of the decade, the word emo cropped up in mainstream circles.
In the summer of 1998, Teen People magazine ran an article declaring
"emo" the newest "hip" style of music, with The Promise Ring a band
worth watching. The independent nature of the emo scene recoiled at
mainstream attention, and many emo bands shifted their sound in an
attempt to isolate themselves from the genre. In the years that followed,
Sunny Day Real Estate opted to shift to a more prog-rock direction,
Jejune aimed for happy pop-rock, and The Get Up Kids and The Promise
Ring released lite-rock albums.

While "indie emo" almost completely ceased to exist by the end of
the decade, many bands still subscribe to the Fugazi / Hüsker Dü model,
including Thursday, The Juliana Theory, and Sparta.


Third wave (2000-present)
At the end of the 1990s, the underground emo scene had almost entirely
disappeared. However, the term emo was still being bandied about in
mainstream media, almost always attached to the few remaining 90s emo
acts, including Jimmy Eat World.

However, towards the end of the 1990s, Jimmy Eat World had begun to
shift in a more mainstream direction. Where Jimmy Eat World had played
emocore-style music early in their career, by the time of the release
of their 2001 album Bleed American, the band had downplayed its emo
influences, releasing more pop-oriented singles such as "The Middle"
and "Sweetness". As the public had become aware of the word emo and
knew that Jimmy Eat World was associated with it, the band continued
to be referred to as an "emo" band, despite their objections.
Newer bands that sounded like Jimmy Eat World (and, in some cases,
like the more melodic emo bands of the late 90s) were soon included
in the genre.

2003 saw the success of Chris Carrabba, the former singer of emo
band Further Seems Forever, and his project Dashboard Confessional.
Despite musically being more aligned to the singer songwriter school,
Carraba found himself part of the emerging "popular" emo scene.
Carrabba's music featured lyrics founded in deep diary-like outpourings
of emotion. While certainly emotional, the new "emo" had a far greater
appeal amongst adolescents than its earlier incarnations.

With Dashboard Confessional and Jimmy Eat World's success, major labels
began seeking out similar sounding bands. Just as many bands of the
early-to-mid 1990s were unwillingly lumped under the umbrella of "grunge",
some record labels wanted to be able to market a new sound under the word emo.

At the same time, use of the term "emo" expanded beyond the musical genre,
which added to the confusion surrounding the term. The word "emo" became
associated with open displays of strong emotion. Common fashion styles
and attitudes that were becoming idiomatic of fans of similar "emo" bands
also began to be referred to as "emo". As a result, bands that were
loosely associated with "emo" trends or simply demonstrated emotion
began to be referred to as emo.

In an even more expanded way than in the 90s, emo has come to encompass
an extremely wide variety of bands, many of whom have very little in common.
The term has become so broad that it has become nearly impossible to
describe what exactly qualifies as "emo".

The classification of bands as "emo" is often controversial. Fans of
several of the listed bands have recoiled at the use of the "emo" tag,
and have gone to great lengths to explain why they don't qualify as "emo".
In many cases, the term has simply been attached to them because of
musical similarities, a common fashion sense, or because of the band's
popularity within the "emo" scene, not because the band adheres to emo
as a music genre.

As a result of the continuing shift of "emo" over the years, a serious
schism has emerged between those who relate to particular eras of "emo".
Those who were closely attached to the hardcore origins recoil when another
type of music is called "emo". Many involved in the independent nature of
both 80s and 90s emo are upset at the perceived hijacking of the word emo
to sell a new generation of major label music. Regardless, popular culture
appears to have embraced the terms of "emo" far beyond its original intentions.

In a strange twist, screamo, a sub-genre of the new emo, has found greater
popularity in recent years through bands such as Thrice and Glassjaw.
The term screamo, however, was used to describe an entirely different genre
in the early 1990s, and the new screamo bands more resemble the emo of the
early 1990s. Complicating matters further is that several small scenes devoted
to original screamo still exist in the underground. However, the new use of
"screamo" demonstrates how the shift in terms connected to "emo" has made
the varying genres difficult to categorize.

The difficulty in defining "emo" as a genre may have started at the very
beginning. In a 2003 interview by Mark Prindle, Guy Picciotto of
Fugazi and Rites of Spring was asked how he felt about "being the creator
of the emo genre". He responded: "I don't recognize that attribution.
I've never recognized 'emo' as a genre of music. I always thought it was
the most retarded term ever. I know there is this generic commonplace that
every band that gets labeled with that term hates it. They feel scandalized by it.
But honestly, I just thought that all the bands I played in were punk rock bands.
The reason I think it's so stupid is that - what, like the Bad Brains weren't emotional?
What - they were robots or something? It just doesn't make any sense to me."
