Named in tribute to the early-'90s adolescent rap duo Kris Kross, Dutch trio Kris Kross Amsterdam started out as a throwback DJ event series before developing into a dance-pop group, performing a party-ready mix of rap, funk, dancehall, R&B, and house. They scored international chart hits with singles like "Sex" (2016) and "Whenever" (2018).
KKA was created by brothers Jordy and Sander Huisman in 2011 when the duo established a club night in order to play the music they grew up with rather than the popular dance music that dominated the club scene. Spinning a diverse mix of R&B, hip-hop, funk, and house, the concept turned out to be a success, and the duo sold out many club nights in Amsterdam. After several years of gigs and mixtapes, as well as establishing a clothing line, the duo began collaborating with MC Yuki Kempees and working on original material in 2014. KKA signed to Spinnin' Records and released the trap-tinged R&B single "Until the Morning" in 2015. Second single "Sex" followed in early 2016, a quasi-cover of Salt-N-Pepa's "Let's Talk About Sex" featuring assistance from Los Angeles' Cheat Codes. The track was an international hit, reaching number two in the group's home country and the Top Ten in the U.K. and Ireland.
