The term “breakdancing” referring to the breaks in music and the movements
performed during the breaks, emerged and became popular in New York.
It was actually James Brown, who inspired dancers with an acrobatic dance
when in 1969 he performed on stage a dance with high-energy moves to his song
Get on the Good Foot.
The Good Foot remained popular until about 1977, when the Freak took over.
