C&K, the singer-songwriter duo formed by CLIEVY and KEEN, make their debut at Billboard Live Yokohama. They debuted with a mini-album in 2008, and achieved major debut in 2010 with the single "Tsuyuake Sengen" (梅雨明け宣言). Rooted in black music such as disco, funk, soul, and reggae, their music blends a wide range of genres—from folk and 1980s kayōkyoku to club music—captivating listeners up to the present. Among their representative songs are the track "Dorama," used as the theme for the drama "Survival Wedding," the live staple "Endless Rondo," and the vocal-powerful ballads "Mikan Heart" and "Y." They have been actively performing nationwide with entertaining live performances. In addition, they have written songs for artists including King & Prince, Snow Man, and Momoiro Clover Z. Let the two's overwhelming and soulful voices envelop the venue as you enjoy a one-night-only premium stage.
