The Rock Steady Crew United States
The Rock Steady Crew was one of the most influencial breakdance crews out there at their time. The original founders were Jimmy D and Jojo, two early popularizers of breakdancing. Although breakdancing has since become a well-known subculture, in the late 1970s it was little known outside of New York, as such their early rivals were from the other boroughs of New York. In the beginning, membership in the crew was only granted by battling with another Rock Steady member; it was a competition few people won.
Come back in a few weeks, it's more than likely that a debut album will be released soon.
