Rock band KOXX that has held its position as one of the leading hallyu band dominating Korea's and international festivals will participate in Japan's "Summer Sonic Festival" for two consecutive years.

KOXX will be performing at the "Summer Sonic Festival" on Saturday and Sunday. KOXX, who gave off a good impression on "Island Stage Asian Calling" is performing on the main top three stage "Sonic Stage" this year.

KOXX received a lot of love calls from places like Thailand, Japan and countries from Europe. They performed at "Singapore Mosaic Festival," "Beautiful Mint Life," "Green Plugged Seoul," and "Rainbow Island Music & Camping Festival" just this year alone.

On the other hand, KOXX is going to perform on "Korea Live Music Festival," and "Let's Rock Festival" this September.
