Think of this as a light primer to House Music in Chicago.
Deep House:
In a nutshell, it's more mellow than the other forms of House Music. A lot of Deep House is the old disco tracks from the mid-late 70's and early 80's. Examples from my list include:
Spring Affair - Donna Summer
Vertigo/Relight My Fire - Dan Hartman
I Need You - Sylvester
"Old School" House
(YoSteve could back me on this one). Old School House is Technically considered House Music that was released between 1986-1988. But I tend to include the stuff from '83-'85
The lyrics can be repetitious and sometimes sampled, but the beats are good.
Examples:
Mix Your Own Stars - 117 (Actually released in 1985, but if played at a party, it will pack a dance floor)
No UFOs - Model 500 (You might have heard this one in a commercial for the Ford Focus)
"Hip House"
Debuted in 1988 (even though there were some earlier examples). Technically, it was the fusion between Rap and House.
Examples:
Pump Up The Jam - Technotronic
Get Up - Technotronic
Get Busy - Mr. Lee
Ghetto House
I can't tell you when it debuted but I can tell you that it is an offshoot of House. It's often referred to as "booty music." I tend to refer to it as Chicago's version of Miami Bass.

The prevailing theme is sexual innuendo and the language reflects it. But the thing with Ghetto is it has a fast-paced, driving beat. In some ways, it can remind you of Progressive House or Techno.
Example:
Watch It - Robert Armani (It's instrumental)
With this in mind, don't be surprised when I start adding more and more house to the list.
