Eun Ji Won opened up about his first solo concert in 12 years.

At his 'Eun Ji Won 2019 Concert - On Fire' at the Kyung Hee University Grand Peace Palace in Seoul on July 28, Eun Ji Won said to his fans, "Thank you so much for these past 2 days since yesterday. My last solo concert was 12 years ago. I was trying to give more of a hip hop feel for this solo concert for the past 12 years, I've tried hip hop music a lot for my solo promotions. Still, I have a dance singer background with Sechskies, I prepared fun dance songs for the opening."

On his concert title 'On Fire', he said, "Because I've gotten older and have more experience, I feel like my passion has lessened a bit. I named it that to mean that I shouldn't forget that passion. I'll make a concert where I can tell you a lot of my own personal stories."  

Eun Ji Won made a solo comeback with "I'm on Fire" this past June.
