childish gambino
Childish Gambino (Donald Glover, speaker/rapper/writer); Ludwig Göransson (recorder/producer).
Childish Gambino's couplet, which exercises the vocal technique of pauses in pace, is an excerpt from the rap song "I Be On That" which was released within his third mixtape, "Culdesac." While the original recording took place in a studio session, this audio clip was accessed from YouTube (see "Source" for details).
