This is only halfway serious, and I didn't write it, so if you're bummed, stop emailing me already.
 

* [ORIGINAL EMO]
Emo Philips, spun comic with bizarre penchant for proto-mod/indie
fashion.. origin unknown.. guested on episode of Miami Vice alongside Phil
Collins in mid 80s.  "E = MO^2" record being the only audio token of era.

* [FIRST WAVE EMO]
Rites Of Spring , Embrace, et al.  DC. Lots of East Coast kids in rock
bands who drank soft drinks and made sure punkers who threw shoes on
stage during the show got them back safe and sound.  Sulking in a rock
context is therefore invented.

* [SECOND WAVE EMO]
Nation of Ulysses, early Unrest.  DC.  Basically the kids that
were freshmen in high school while the First Wavers were about to
graduate.  Emphasis on tributes to soul figures, extreme protest methods,
and jazz record labels, while making music with no connection to
any of the above.  Inside jokes about The Ice Cream Shoppe and other
DC landmarks encouraged.  Set the stage for neo-indie-pseudo-soul bands
that all pretty much sound like that early Can record "Can Delay 1968".

* [OLYMPEMO]
Lync, Mukilteo Fairies.  Northwest US.  Cigarettes.  Lots of them.
Calvin Johnson screwed my girlfriend this week.  Grrrrrr.
Jocks and lumberjacks suck.  Satan destroy them.  "Oh yeah?
I'll show *you* sulking."

* [SAN DIEGO SCREAMO]
Antioch Arrow, Heroin, The Locust.   Lots of kids with greasy short black
Romulan hair, with shiny black pants, white work shirts, and no butts...
very sick of having to drive 2 hours north to see any good show because
of no all ages clubs in area.  Anger Anger.  Handing out poetry with
plagiarized Cure and Public Image Limited lyrics at shows a plus.  Sets
new record for speedy breakup-recombine-and-regroup times within a rock
scene.

* [SANTA CRUZ EMO]
Nuzzle. Lots of beeer, fisticufs bluff et al.  I'm borrowed my parents'
beamer.  Let's drive to the Chevron in Salinas and have a corn dog.

* [NOUVEAU SUBURBAN STRAIGHT EDGE EMO]
Very new Crate half stacks. Sixteen year-old girlfriend sincerely wearing a
brand new tie-dye Zep t-shirt.  Very well kept hair and clothes, almost
hardcore gangster in their appearance.  But these are sweet sincere, clean
cut kids, just trying to break out of hypocricy of American life, man.
Baggie jeans, brand new sketchers...sound like Slayer.

* [PORTLAND EMO]
Become an experimental film student, or start a free jazzband, or just
keep doing temp work and getting stoned with members of Crackerbash.

* [EMO ACCORDING TO SPIN OR ROLLING STONE]
Sunny Day Real Estate. Promise Ring, Jejune, Texas Is The Reason, etc.
Basically, alternative grunge rock but the songs are slower and longer.
Emphasis on REO Speedwagon influences, fluorescent skating company
t-shirts, and pant pocket wallet chains.  Gap ads.
