After a summer of releases from the full group, several members of Girls' Generation will fill up the remainder of the year with new music. 

Girls' Generation's Taeyeon and Tiffany have both announced their upcoming releases as solo singers.

With Kim Taeyeon already in the middle of recording her solo album, Tiffany Hwang has been revealed as the girl group's second member to work on her own music project.

According to an industry insider on Sept. 3, Tiffany has been preparing for her solo album while currently doing promotions with Girls' Generation. The album is expected to be released in November, following the release of Taeyeon's solo album in October. 

Promotions for the Girls' Generation's latest single "Lion Heart" and album of the same name will wrap up at the end of September while project group TaeTiSeo - consisting of both Taeyeon and Tiffany as well as Seohyun (Seo Ju Hyun) - is slated for a December comeback. 

With all these comebacks and new releases, it would seem that Girls' Generation is determined to dominate the K-pop music world for the second half of 2015.

The group made a comeback in July with "Party" and later released their full studio album "Lion Heart" in August which included two title tracks "Lion Heart" and "You Think."
