“Growl” was the crown jewel in boy band EXO’s fantastic 2013. While past singles like “Mama” and “Wolf” were based around complex concepts and busy production, “Growl” used a sparse, Southern hip-hop beat that let the 12 boys’ talents shine through. A blend of rap, R&B melodicism and pop hooks, the breakout single had something for all listeners. Its accompanying video focused on a straight-forward, one-take video, again allowing for EXO’s talents — in this case, choreography — to shine, not detracting from over-the-top high fashion. Along with high interest from the United States — the boy band is the newest act to land among the top-selling K-pop tracks in America — “Growl” solidifies EXO as the act to watch in K-pop’s continuing international advancement.
