Hip-hop’s ‘80s pop takeover had a slew of ripple effects—and few were as effective at getting people on the dance floor as the rise of new jack swing, which fused the strutting attitudes and electrified beats of hip-hop with the deep grooves and soulful vocals of R&B. In the ‘80s, producers like Teddy Riley and the team of Jimmy Jam and Terry Lewis led the way, spicing up R&B tracks with synth-drum hits and splashy keyboards; as hip-hop boomed in the ‘90s, new jack swing evolved alongside it, amping up its street edge and sex appeal.
