K.O's latest single from his recently-released album PTY UnLTD is the song "Citi Boi." The South African rapper recently highlighted the song with a new music video. The video is a mashup of visuals for both "Citi Boi" and "4AM," which comes towards the end of the clip.

"Citi Boi" is quintessential K.O, as the song references both trap by way of its distorted bassline and kwaito. K.O's combination of melodies and raps is what defines PTY UnLTD.

"Citi Boi" is a summer-ready anthem, and the visuals live up to its feel. K.O and some women friends have a great time in a water park.

On "4AM," K.O flirts with amapiano, the new house music genre that has held the streets captive. The song is built on a sample of kwaito legend Spikiri's "Money Talks."

The visual seems to be a continuation of the day depicted on "Citi Boi," as it takes place at night and shows more festivities.

PTY UnLTD is K.O's third studio album since he went solo after being a member of the group Teargas in the mid-2000s and early 2010s. The album is a new chapter for K.O—his first two albums were titled Skhanda Republic 1 and 2. In the albums, the emcee was exploring the subgenre he created with his Cashtime Life family.
