Mika Nakashima rose to fame in Asia through the early ‘00s with her smooth, mature voice and jazz- and R&B-inspired sensibility. Her tender ballads have been covered by artists from China, South Korea, and Singapore. While these slow songs are her mainstay, she's also famous for her turn as the hard-rocking heroine of the 2005 movie Nana, whose soundtrack yielded her first No. 1 single, “Glamorous Sky.”
