KARA’s sister group, Rainbow, will be making its comeback to the Korean music scene this summer.

An associate from the girls’ agency, DSP Media confirmed on May 25th, “Rainbow will be making a Korean comeback as early as July or August.”

The agency described that the ladies are fast paced at work producing their new record, and they are very carefully choosing their title song and subtracks, as it is their first return in a lengthy while.

“Their title song has not yet been determined, so we cannot explain what kind of concept it will be just yet. However, it will be full of colors that are characteristic of Rainbow”, a rep added.

Meanwhile, Rainbow has performed well on the Japanese charts with songs such as “A”, “Mach”, and more.
