The music first developed primarily in the Latino communities of New York City in the early 1980s. Initially, it was a fusion of synthetic instrumentation and syncopated percussion of 1980s electro, as favored by fans of breakdancing. It was also influenced by sampling, as found in hip hop music. Key influences include Afrika Bambaataa & Soul Sonic Force's "Planet Rock" (1982) and Shannon's "Let the Music Play," the latter of which was a Top 10 Billboard Hot 100 hit in early 1984.[2] Several freestyle songs entered the Billboard Hot 100 charts during 1987, marking this as the first year that freestyle got acknowledged on US radio stations. Songs such as "Come Go with Me" by Exposé, "Show Me" by the Cover Girls, "Fascinated" by Company B, and "Silent Morning" by Noel helped freestyle go mainstream that year. By 1992,[3] however, house music, which was based partly on disco rhythms, challenged the relatively upbeat, syncopated freestyle sound. In the early 1990s and on through the 2000s, the electro and Latin hip hop influences of freestyle were supplanted by house music.
