SBS "K-Pop Star 2" contestants Two-Thousand WON staged a surprise performance on the streets of Hongdae, releasing the performance video.

Two-Thousand WON posted the guerilla busking clip on their official Facebook and Twitter accounts. They introduced themselves, revealing the reason behind the name Two-Thousand WON. They had started performing in the streets when they were freshmen in high school; 2000 won(approximately $2), was their first income.

The busking was held in Hongdae on April 12 to perform mini album title song "I Hate Seoul" on the streets. Two-Thousand WON performed debut song "I Hate Seoul" and "I Have a Girlfriend" live, drawing out enthusiastic responses from the crowd gathered. Two-Thousand WON's popularity could be noted by the people gathered around the performing members.

Choi Ye Geun, who Two-Thousand WON met through "K-Pop Star: Season 2", joined Two-Thousand WON by playing the keyboard during the performance. Although the keyboard unexpectedly turned off during the performance, the performers did not lose their calm, finishing the song acapella.

Two-Thousand WON, who clung on to their aspirations to become musicians by busking on the streets, stated: "This is our first busking since debut, and I'm more thankful that I've been given a chance to perform like this again. We won't forget the hunger for music we felt when we were still busking, and meet fans like this more often".

Meanwhile, Two-Thousand WON debuted with their first mini album "I Hate Seoul", launching their first debut performance on SBS "Inkigayo" on April 13.
