Stankonia, OutKast’s fourth studio album, was released on October 31, 2000. It was critically acclaimed by critics and artists alike, producing three iconic singles: “B.O.B,” “Ms. Jackson” and “So Fresh, So Clean.” The album was recorded in their Atlanta studio, Stankonia Studios, and featured production from Earthtone III and Organized Noise. André 3000 spoke on the convenience of owning their own studio, saying: “You can sit there and fuck with just a kick and a snare all day long if you want to … You’re not working on the clock. Really, you’re just working on your mind.” The track “Snappin' and Trappin'” featured a verse from a then-unknown rapper Killer Mike, who later would go on to form ½ of the rap duo Run the Jewels. Big Boi was impressed by him, saying: “When I first heard him spit, his voice was just so commanding. He’s a very intelligent guy.” Stankonia debuted at #2 on the Billboard 200 and has been certified quadruple platinum. Its lead single, “B.O.B.,” peaked at #69 on the Hot 100 but was later banned from many radio stations because of its controversial subject matter. It won Best Rap Album at the 2002 Grammy Awards, and “Ms. Jackson” took home the Best Rap Performance award. On the 20th anniversary of the album, they dropped a deluxe version of the album, including remixes and acappella versions to each of the singles.
