SISTAR joins the list of female groups who are making their comeback this month.

The four-member K-Pop girl group will join 4Minute's HyunA, Girl's Day, Secret, and KARA on the list of anticipated summer combacks in the K-pop industry.

SISTAR, who debuted in 2010 under Starship Entertainment, consists of members Hyolyn, Bora, Soyou, and Dasom.

July 21st is the scheduled comeback date that SISTAR has officially announced.

SISTAR chose not to work with their usual producers, Brave Brothers and Duble Sidekick, for their upcoming comeback, according to a report that was published on the Korean news outlet OSEN. Instead, SISTAR is collaborating with composers Rado and Choi Kyu Sung for their new single.

Known for their other hit singles with Duble Sidekick, including "Loving U", "Holiday", "Push Push", "Alone", "Ma Boy", "So Cool" and "How Dare You," fans are wondering what kind of transformation the group will be making by working with a different producing team.

SISTAR has yet to fail the expectations of fans. Their previous summer single "Loving U" topped major music charts in South Korea.

The members continued to keep busy after they were done promoting, "Give It To Me," with each of the ladies focusing on their individual activities. 

Hyolyn released her first solo album, "Love and Hate," collaborating with Mad Clown in the process. Soyou also made musical developments with a duet with Mad Clown and JungGiGo.

Both tracks were major successes. They were nominated for awards and topped the music charts with Hyolyn and Soyou winning first place trophies on popular Korean music programs.

Members Dasom and Bora successfully ventured into the acting industry.

Bora was cast in the SBS drama series, "Doctor Stranger" while Dasom played a role on the KBS drama "Love Rides The Rain."
