SISTAR's Hyorin prepared a sexy jazz performance for the October 27th episode of 'Immortal Song 2'.

The talented idol covered "Cup of Coffee" by the old-school trot duo Pearl Sisters. Viewers were saying that Hyorin managed to turn the trot song into a brand-new sound�reminiscent�of a Broadway production. Her charismatic performance and sexy dance number also impressed the audience.

"Godfather" of rock Shin Joong Hyun commented, "It's extremely difficult to sing and dance at the same time, so I'm very impressed. I thought, 'Our country's music can be interpreted this way too.' It was a very cool performance."

Hyorin ended up receiving the final win, defeating 4men's Shin Yong Jae by 2 votes.
