You could pretty easily make the case that Chicago is the musical center of the United States. Blues, juke and house all originated (at least in part) from the city. Two-Step (or just Steppin) never achieved the national name recognition as house music, but it was a pretty potent strain of R&B that peaked in the middle half of the last decade. Like a lot of music to emerge in the past thirty years, it was a dance first. The music was bright, romantic and highly syncopated. Its great, summery R&B music. It was popularized nationally by R. Kelly in his "Step in the Name of Love" single, but that was really just the tip of the iceberg, as this excellent playlist demonstrates. Rizoh over at Beats did a great job capturing some of the highlights from the scene. Listening now, it definitely feels of a certain time and place, and it seems very out-of-step with the more dour and minimal sounds the genre would adopt in subsequent years, which makes two step even more powerful.
