Kaleidoscope is the debut studio album by American singer Kelis. It was released on December 7, 1999, by Virgin Records, and was produced entirely by the Neptunes. Despite underperforming in the United States, the album saw mild success in certain international markets, including the United Kingdom, where it charted at number 43 and was certified gold. Kaleidoscope was reissued on February 21, 2020, in celebration of its 20th anniversary. The extended digital release features edits and club remixes, including a Neptunes extended remix of "Caught Out There". The physical edition was pressed to translucent orange vinyl and was released in a two-set on March 6, 2020. Critical reception Kaleidoscope received widespread acclaim from music critics. AllMusic editor Jaime Sunao Ikeda rated the album four and a half out of five stars and remarked that 'the album "showcases the development of a great talent [...] It's when Kelis and her production team create tracks that best fit her voice and uniqueness that the end results are outstanding. Although comparisons to Neneh Cherry are inevitable, she does carve out a niche for herself, armed with undeniable talent." NME called Kaleidoscope a "futuristic, visionary, multi-layered work of R&B, funk, soul and rap, furnished with an inspirational, psychedelic spirituality, rarely seen but desperately needed in these cynical times" and concluded: "Uplifting, magical, genre-bending music, if there’s a better debut album this year, bring it on. We need more like this." Q magazine's Kerry Potter described Kaleidoscope as "an album that packs punches of the Mike Tyson variety and oozes confidence from every beat [...] Kaleidoscope isn't just a promising debut, it's an inspired one." Entertainment Weeklys Britt Robson found that the album "fleshes out her persona with petulant sass and roller-rink whimsy, pegging her romantic maturity halfway between Brandy and Mary J. But what lingers are the minimalist staccato beats from production duo The Neptunes." Rolling Stone critic Arion Berger wrote that Kaleidoscope was "too musically adventurous and emotionally ambivalent to employ any one attitude. Plumbing retro styles is the easy resort of the hip-hop eclecticist, but somehow Kelis' background in jazz, gospel, rock and R&B; brings a deeply felt sonic futurism to her debut album [...] The Neptunes makes this interplanetary power-girl mix sound both danceably down-to-earth and shockingly new." In 2020, the magazine ranked the album at number 391 on their updated list of the "500 Greatest Albums of All Time". Commercial
