Hyun Jyu-ni, Scarlet mojo-Pin (BH Entertainment)

Singer and actress Hyun Jyu-ni and electric music duo Scarlet mojo-Pin released their first single, “Ez Come Ez Go,” on Wednesday.

The song features electro-punk tunes and “starts like a 1970s spy film soundtrack,” according to her agency BH Entertainment. Hyun took part in composing the song, the agency said.

The 32-year-old singer debuted as a lead singer for four-member girl rock band BellaMafia, which released its album “Overstep” in 2008. TV director Lee Jae-gyu spotted her in musical Bandits and cast her as a flutist in television series “Beethoven Virus.”
