Phase three: "hardcore emo." Heroin, Antioch Arrow, Mohinder, Honeywell, Reach Out, early Portaits of Past, Assfactor 4, Second Story Window, End of the Line, Angel Hair, Swing Kids, Three Studies for a Crucifixion, John Henry West, Guyver-1, Palatka, Coleman, Iconoclast, some Merel, some Clikatat Ikatowi, etc.
-Hinted at in New Jersey in 1990 (Merel, Iconoclast). Starts for real in San Diego in 1991 with Heroin, comes to SF Bay in 1992 (Reach Out, Mohinder, Honeywell, Portraits of Past, John Henry West), hits Philly, Florida, New York, and the rest of the East Coast a little bit.
-Similar to punk vs. hardcore punk - faster, louder, harder, much more intense and single-minded. Most of these bands play extremely fast, and introduce the "chaos" concept to hardcore. This is extremely abrasive music, with vocals screamed at the physical limit of the vocal chords. The guitars are distorted to the point that notes and chords are hard to recognize - although often the guitarists don't even play notes, instead making piercing, staccato bursts of noise, squeals of deafening feedback, or a wash of strummed dissonance. The bass often has quite a bit of distortion as well, unlike straight emo. This is everything emo done more so - sometimes so totally over the top that the band 's songs are not even recognizable when performing live. Antioch Arrow, for instance, thrashed about so much on stage that they sounded less like a band than a giant amplified blender. After each song, they had to retune every string, and usually had knocked over a good fraction of their equipment. These shows tended also to be quite short for reasons of the band's physical endurance.
-All the other notes about emo records, shows, economics, etc. apply to hardcore emo too. It's very much simply a subset of emo. In my eyes, this was the ultimate expression of the form. There was a frantic, primal quality to a band like Heroin that could just reach through your ribcage and squeeze your heart like in the Temple of Doom. I never found that in any of the other types.
Phase four: "post-emo indie rock" and post-emo post-hardcore. Sunny Day Real Estate, Christie Front Drive, Promise Ring, Mineral, Boys Life, Sideshow, Get-Up Kids, Braid, Cap'n Jazz, then later Joan of Arc, Jets To Brazil, etc. Lots of Caulfield and Crank! Records bands, more lately a lot of stuff on Jade Tree for instance.
-Anyone that claims to like both straight-edge and emo is probably talking about this kind of emo. Starts out near Colorado and Seattle, explodes all over the Midwest, then onward to New York, etc. In fact an early term for this kind of music was "midwest emo," as these bands seemed to come out of nowhere towns in Missouri, Kansas, Colorado...
-Musically, tends toward a lot of loud/soft interation, but a lot of softly-sung vocals and very little screaming or harshness. Lots of catchy, poppy guitar riffs, happiness or at least melancholy, and a particular fascination with off-key, cutesy boy vocals. This is where the phrase "twinkly guitar parts" comes from - lots of pretty major-key arpeggios, light drumming, and some amount of crooning. It sounds like a recipe for cheeze, and sometimes is. I remember reading a review of the early Christie Front Drive 12" that said, "this is what emo kids listen to when they make love." It was a nice alternative to a steady diet of hardcore.
-There is a valid element of emo in the vocals here (along with occasional octave chord). It's not as easy to identify as the mournful screaming in the original emo style, tending to consist more of greatly drawn-out phrases detailing very emotional lyrics with ironically light and poppy singing.
-Sunny Day Real Estate came up with a very original post-hardcore meets emocore at an indie rock show sound. This inspired a spawn of imitators even more shameless than the Fugazi and Quicksand clones. Which leads one to observe: post-hardcore emerged when the hardcore scene tired of the same seven-year-old sounds inspired by a few innovative hardcore bands. A few innovative post-hardcore bands come out with a totally new sound out of nowhere (Fugazi, Quicksand, SDRE, Drive Like Jehu), and spawn legions of imitators. Basically straight out of Thomas Kuhn's theories...
-By 1999, this type of music had achieved a fan base far larger than any of the original emo stuff. In fact, that's what prompted me to write this website in the first place - the glut of info on the web about this and the lack of a historical perspective. Statistically, you the reader are most likely to be familiar with this type of emo. In the years since then, it's only grown far, far bigger. Jimmy Eat World and Thursday are in regular rotation on MTV and many corporate alternative radio stations, and sappy music like this Dashboard Confessional fellow is pulling in a whole new audience. This is well on its way to becoming a major demographic market, soon after which we'll see a lot of new bands with zero real connection to the original underground scene (unlike for instance Jimmy Eat World, who used to open at every emo show in Phoenix way back in 1994).
Phase five: post-emo hardcore? The "emo" style detailed above has been dead since around 1995, when new emo bands stopped forming and the old ones broke up. Most people in bands nowadays seem to regard pure emo to be overstated and quite cheezy (of course, this opinion has had its adherents all along...). The "emo scene" since has taken a few different directions. One is the ultra-heavy, ultra-fast wall-of-noise attack blending elements of grindcore and Neurosis-style apocalyptic chaos with bleeding-vocal-chords screaming: Jenny Piccolo, Union of Uranus, One Eyed God Prophecy, Makara, Living War Room, Orchid, Reversal of Man, Usurp Synapse, To Dream Of Autumn, etc.
Another trend has been to explore analog synthesizers and mod/goth/new wave sounds - post-emo style-rock? Das Audience / The Vue, VSS, Slaves, Crimson Curse, etc. Mostly a California thing originally, this has ballooned and is one of the vibrant growing scenes in indie music as I write this. The Faint, The Hives, The White Stripes, Milemarker, and even some mainstream music like The Strokes are reviving late 60s/early 70s rock and roll (Lou Reed and Velvets style, maybe a bit of Rolling Stones) with the emo fashion sense and a cynical underground sneer.
The vocal intensity of emo has been very influential on non-emo styles, as well. It has crept into new-school metallic hardcore quite a bit: Downcast, Struggle, Groundwork (AZ), Converge, Threadbare, Unbroken, Guilt, Botch, Fall Silent, Cable, Time in Malta. The chaos, power, and bleeding vocals of hardcore emo have similarly influenced non-emo ultra-hardcore bands: Jihad, Coalesce, Dillenger Escape Plan, etc.
Traditional East Coast hardcore and straight-edge has always been the most derisive critic of emo, befitting the male-oriented macho reputation of that scene. However, a few harcore/sXe bands have integrated emotional lyrics, octave chords, and a softer vocal delivery into their music. For example, listen to the later Turning Point, Endpoint, and early Lifetime records, as well as newer groups like Falling Forward, Split Lip, Shai Hulud. Many people with only a hardcore/sXe background consider these emo-inflected HC/sXe bands to be "emo" bands, but recognize the "emocore" category as detailed above as poppier and more rock versions of hardcore. They also tend to classify straight emo and hardcore emo as simply punk (based mostly on the low production values and the lack of heavy rhythms present in all HC/sXe). "Emo" is a catchall category for this scene - they classify almost all indie rock (Seam, June of '44, Codeine, etc.) and post-hardcore (Quicksand, Shift, Texas Is The Reason, Sensefield) as emo as well!
Screamo - I mentioned this under the "emo" section, however in recent years some bands have sort of re-integrated some diverse emo influences. With the band Saetia, for instance, you'll hear heavy fast screamed hardcore parts, with abrupt starts and stops and guitar focus more from the classic emo side, and quiet, twinkly melodic parts in between. "Screamo" has become sort of a catchall modern category for all of this for the few new bands playing this style, often used by younger fans who weren't around when the screaming vocal thing was new and unique.
