Having conquered the charts with the success of her debut album, SBS' 'K-Pop Star' finalist Baek Ah Yeon has finally held her debut stage. She performed "Sad Song" from her debut mini-album 'I'm Baek' to an adoring audience.

Prior to her performance, Baek Ah Yeon commented, "I'm very nervous and excited as I'll be holding my first stage as a real singer… I'll show a performance that will hopefully match up to the amount of work I've put into it and the expectations of fans. Thank you."

She certainly did not disappoint, performing with such grace it's hard to believe she is only one week into her debut.
