Japanese R&B singer Crystal Kay has been expanding her horizons of late. From performances at London’s Royal Albert Hall, to collaborating with Far East Movement in Orlando, Florida, the 27-year-old singer has been spreading her wings internationally – most recently via “Dance Earth,”  in which she took to the stage for the first time as a character in a musical theater production. BLOUIN ARTINFO caught up with Kay to discuss her coming English-language album, and the decline of R&B in Japan.
