Around 1,200 people attended the concert, the theme of which centered around reminiscing on the innocence of one's youth. The singer belted out her most popular singles, including, "Eraser", "I Tried Everything", "365 Days", and more, providing nothing short of a rich performance for everyone who attended her modest yet special concert. ALi's stage was made more lively with guest appearances by Huh Gak and Hwang Chi Yeol who had starred with her on 'Immortal Song'. 

One concertgoer couldn't hide his awe when he said, "I think ALi's vocal chords are made out of steel. It was a two-hour long concert, but she sang for three hours, and there was no change in her voice throughout." 

The singer, whose first solo concert wrapped up with great success, is said to be making a comeback this October, so watch out for ALi's steel vocals!
