SISTAR performs and sits down for an interview on 'Yoo Hee Yeol's Sketchbook'

SISTAR is back and sexy as ever as they performed summer track "Touch My Body" on this week's 'Yoo Hee Yeol's Sketchbook'! �In addition, Hyorin and Soyu did a hauntingly beautiful cover of Christina Aguilera's "Hurt."

During the interview portion, Hyorin revealed that she had composed quite a lot of songs, all of which the agency listened to but turned down on the grounds that they were basically not mainstream enough as she likes to experiment with R&B and hip hop.�

Soyu elaborated that because the songs were Hyorin's personal compositions, they were made for her and her only. �Understandably, this may make it a bit harder for people to approach the songs, but fans, nonetheless, surely want to hear some of her compositions on the girls' album soon!
