SISTAR put on an exhilarating show for more than 4,000 fans this weekend with their second solo concert 'S.'

The show was held at Seoul's Olympic Hall on October 12.

The concert opened with the girl group's latest single "Give it to Me" and the ladies followed it with high-energy performances of "Girl Do It" and "Push Push."

The concert hall was full of thousands of screaming fans who also had the opportunity to enjoy special performances from the members including Hyorin and Soyu's cover version of Rihanna's song "Diamonds."

Bora joined Hyorin for their SISTAR19 sub-unit tracks "Ma Boy" and "Gone Not Around Any Longer" and then showed off her rapping ability with a version of Lee Hyori's tune "Miss Korea."

Soyu proved her singing talents with another Rihanna cover, this time "We Found Love" and Dasom wowed the audience with a gentle cover of "Like a Star" by Corinne Bailey Rae.

Those weren't the only covers of the night as Hyorin took to the stage to showcase her talent yet again with a song from her personal idol Beyonce, "End of Time."

Exciting the Olympic Hall even more, K.Will and Baek Ji Young made special guest appearances and performed alongside SISTAR on stage.

After the amazingly successful concert, the members shared their thought with fans.

"I was nervous because this is our second concert," explained Soyu. "I was so excited that I didn't know what I was doing on stage. It was an overwhelmingly happy concert."

Soyu also added that she would very much like for the group to hold more concerts in the near future.

"I had fun writing my own rap lyrics and rearranging songs for our solo stages," said Bora. "I was really excited to see the audience having fun during those special stages."

Dasom added a bit about the concert title, 'S,' saying, "Like the letter S which stands for sexy, swag, special, and more - we want to show a sexy, cute, and charismatic image."

Congratulations to SISTAR on their successful second solo concert, and we all hope to see more great performances form the group in the future!
