The hip-hop act Migos have been steadily buzzing since their 2013 smash “Versace” rediscovered the power of the triplet flow over booming production. Not unlike the double-time cadence popularized by Bone Thugs-n-Harmony and reinvented by A$AP Rocky, the “Migos flow” set into motion a cadenced wave that seeped into the cadences of everyone from Drake to Kanye to Ab-Soul. Their widely acknowledged cultural influence even ignited a fiery and only partly joking “Migos > The Beatles” debate on social media — John Lennon never got a hundred thousand retweets, folks pointed out. Generating a buzz from mixtape singles like “Fight Night” and “Look At My Dab,” which triggered the worldwide “dabbing” craze, Migos shot into the spotlight in late 2016 with the unexpected smash success of “Bad and Boujee” and has hit arenas for this fall tour.
