The refreshing and lively girls are back for a fun and joyful summer. Sistar is releasing their special summer album [LOVING U] for everyone to enjoy during this summer season. Promising a hot summer, they are ready to offer fun and joyous energy with yet a different charm from what they have shown us so far. The music video for "LOVING U" was shot entirely in Hawaii. Containing the refreshing and natural charm of the Sistar members with the famous gifted scenery of Hawaii as its background, the music video for "LOVING U" will no doubt fix viewers' eyes on the screen. The special summer album [LOVING U] was produced by the hot rising producer Eedan Yupchagi. Having topped charts with "Voice" and "Good Boy" by Baik Ji-Young and "This is War" by MBlaq, Eedan Yupchagi spent a lot of effort in coming up with "LOVING U" for Sistar, emphasizing their cute and sexiness, with the acoustic sound of the brass coming in harmony with the guitar and synthesizer. Moreover, "Queen City Horns", touring with the pop sensation, Prince, took part in the brass for a more well-rounded sound, reminding us of the sweet emotions of love like a midsummer night's dream.
