On April 28, SISTAR Bora's agency�Starship Entertainment revealed more photos of talented rappers Bora, Kisum, Lil Cham, and JACE.

The caption reads, "Hip hop girl power! SISTAR Bora X Kisum X Lil Cham X JACE and Adoonga's special collaboration 'Feedback's photoshoot has been revealed! Everyone, give some feedback!"

The photos reveal the four girls looking as powerful and cool as ever. Previously released photos had shown the girls looking tough in black and white, and while these photos are a big contrast, the four rappers still retain their tough, cool image. Bora especially stands out with her curly, blonde hair as she bites her lip.

The four girls plus Adoonga have just released their "Feedback" MV, and it's become an instant hit!
