After a brief stint as an R&B group, KARA hit their stride with a string of Sweetune-produced singles that established an upbeat, synth-pop style. That sound has led to major success not only at home, but in the Japanese market, where KARA are considered leading ambassadors of the K-pop boom. Over the years, KARA have continued to evolve, as the peppy, cutesy concepts of their earlier songs have given way to a more mature, polished aesthetic.
