A Rapper Who Spoke Quietly and Had a Big Impact

One of the ironies of recent music history is that Migos, the band of Atlanta rappers who reshaped hip-hop in the mid-2010s, is known for something called the “triplet flow.” The term is musicological, describing the convulsive vocal cadence that took over pop thanks to them. But the term is also apt given that Migos were a trio related by blood. They built songs out of the complex interplay of their voices, and they built a brand on the heartwarming sight of three men rising together in a tough and fractious industry.
