The 2000s saw a rise in Chicago juke (also juke house or simply juke), a faster variant of ghetto house which began forming in the late 1980s. Chicago juke songs are generally around 150–165 BPM with beat-skipping kick drums, pounding rapidly (and at times very sparsely) in syncopation with crackling snares, claps, and other sounds reminiscent of old drum machines. The production style is often markedly lo-fi, much like baile funk. Chicago Juke evolved to match the energy of footwork, a dance style born in the disparate ghettos, house parties and underground dance competitions of Chicago. RP Boo, a former footwork dancer, is generally credited with making the first songs that fall within the canon.
