While K-pop continues to gain greater recognition worldwide, South Korea's prolific, small underground-music scene is still struggling to find audiences outside of Seoul.

Folk-rock group Chang Kiha and the Faces have, until now, brushed off the so-called Korea boom and focused primarily on their domestic market.

"The Korean lyrics are very important in our music," says vocalist and band leader Chang Kiha. "One of my main goals is to make our lyrics as Korean as possible. Our priority is to do well in Korea."
