SISTAR sang out their hearts for the DJ DOC special of 'Immortal Song 2'.
They covered the hip hop group's hit song "Beauty and the Beast", and with Dasom, Bora, and Soyu joining Hyorin for the show, their performance especially wowed the crowd. Hyorin commented, "I'm happy that my fellow members can join me on a stage that I stood alone on."
DJ DOC said, "The dance was the best," and "I liked your cover the most. SISTAR's the best."
Despite lasting until the final round, SISTAR lost #1 to Norazo.
