Kilt II

On February 13, 2013, both Iamsu! and Problem, who they had met for the first time at the "Function" video shoot, released a collaboration mixtape, titled Million Dollar Afro.[3] The mixtape was praised by Tom Breihan of Stereogum and Spin named the mixtape one of the best rap releases of 2013.[4][5] On March 5, 2013, Spin named Iamsu! as the tenth "Hottest MC in the Game".[6] The mixtape serves as the sequel to Iamsu!'s third mixtape, 2012's Kilt.[7]

Iamsu! incorporates live instrumentation on Kilt II, which he says "is more musical than anything I've done before. I played instruments on here. I experimented with vocoder. I composed most of the music and worked with a lot of talented musicians. I tried a lot of new sounds."[8] The mixtape's production was primarily handled by Iamsu!, P-Lo and other members of his production team The Invasion.[9] Other individuals that provided production included Trackademicks, Tha Bizness and Exclusive. Guest appearances on the mixtape came from members of The Invasion, HBK Gang, among others such as Problem, Juvenile, Tydollasign, Terrace Martin, Tank, and Mistah F.A.B[8][10][11]

In May 2013 Iamsu! begun his first headlining tour, in promotion of his at the time upcoming mixtape Kilt II.[12] On July 9, 2013, a deluxe edition of the mixtape was released featuring five new tracks, including the Problem featuring "The Realest" and a full remastering and higher audio quality.[13]

Iamsu! premiered the music video for the mixtape's first track, "Father God" via Rolling Stone on July 2, 2013. He explained the background of the song to them saying, "Everybody has their perspective on religion in hip-hop, and lately there's been a lot of talking down on it. So when it came time to write this song, I just felt like praying on the chorus. I believe there is a God and that I owe him a great deal. I've been blessed."[14]

On August 6, 2013, the Tank featuring "Let Go" produced by Tha Bizness, was released as the mixtape's lead single.[15] On October 14, 2013, the music video for "Hipster Girls" was released.[16] On December 3, 2013, "Hipster Girls" was released as the album's second single.[17]

Upon its release, Kilt II was met with generally positive reviews from music critics. Pitchfork Media gave the mixtape a 7.5 out of 10 rating saying, the mixtape "doubles down on all of his strongest and most likeable qualities: Largely self-produced, high-energy, and creative, it shows Iamsu! continuing to transform from a promising, agreeable Bay Area rap figure into a burgeoning star."[19] Spin would also praise the mixtape saying, "As much a showcase of Iamsu!'s production prowess as it is evidence of his unique lyrical skills, the new tape is an enjoyably bumpy ride through treble-y bleeps, bassy bloops, tinny drums, and hard-hustling vocals."[20] The Fader said, Iamsu!'s "laid-back delivery are definitely appealing, but it's the sticky, moody production touches—like distant, eerie synth sparkles, from Invasion member P-Lo, or swelling strings—that make Kilt II so fun and absorbing.[7]
