“Under the Sun” serves as the opening track to Revenge of the Dreamers III and first official collaboration between North Carolina artists J. Cole, Lute, and DaBaby. The rappers boast about their sexual prowess and material possessions over a laid-back instrumental.

Longtime collaborator Kendrick Lamar also makes an uncredited surprise appearance, providing vocals for the song’s chorus.

In March 2019, DaBaby teased a forthcoming collaboration with Cole in an interview with Real 92.3 LA. The song’s accompanying music video was released on September 16th , 2019.
