The pair Clievy and Keen go by C&K, but they're best known across Japan for their sun-soaked party pop, the sort of upbeat fare that can turn even the greyest winter day into a trip to the beach. The two mainly dabble in floor-filling genres such as funk, reggae and contemporary EDM, all drizzled with a tropical feel. Even the quieter moments sound like they wafted in from a campfire on the shore.
