Wreckx-n-Effect were an American hip-hop group, closely tied to producer Teddy Riley and the new jack swing sound, who scored one enormous, saxophone-driven hit. "Rump Shaker", released in 1992, paired a famous sax riff with a party-ready groove, and it became a top-two hit on the US Billboard Hot 100, a defining dancefloor record of the early-90s.
The group were unable to follow it with anything on the same scale, and to the wider world they exist entirely through that one inescapable single.
On streaming, "Rump Shaker" sits near 63 million plays, and one of their other top entries is a radio edit of the same song. Their next distinct track trails far behind. That puts the ratio above 6, past our 5.0 line.
By our measure Wreckx-n-Effect are a certified one-hit wonder. Theirs is a classic new jack swing story: a group who caught the exact sound of their moment with one irresistible, sax-laced anthem that ruled the dancefloor, then faded as the style passed, leaving that single hit standing far ahead of everything else they recorded. Built on an unforgettable saxophone loop, "Rump Shaker" still fills floors three decades on, a new jack swing landmark that has comfortably outlasted the rest of their catalogue.
