Sistar performed Psy's hit song 'Gangnam Style' on their first concert 'Femme Fatale' at the olympic hall.
This was a response to Psy's parody of Sistar's 'Alone' at Psy's 'drenched show' which was held at the Seoul Jamsil Olympic Stadium last August 11, at the secondary stadium.
Here, Psy had received a frenetic cheer from the audience by wearing Sistar's trademark outfits and dancing.
Sistar responded to this parody by singing and performing 'gangnam style'. A representative of Starship Ent. explained, "Seeing what Psy had shown, we've decided to sing 'gangnam style".
Gathered great popularity both performance and vocals addition, Sistar had prepared a variety of pop and a lot of colorful stage for their concert.
