The girls are back.

Ten years after their 2007 debut, the veteran eight-piece troupe known as Girls' Generation (miss you, Jessica!) returned on Friday (Aug. 4) with their sixth studio album in honor of their 10th anniversary, entitled Holiday Night.

The 10 track LP features two lead singles, "Holiday" and "All Night," the latter of which was produced by Kenzie (who also produced their debut single "Into the New World"), and is partially reminiscent of Red Velvet's "Red Flavor. (Surprise: Kenzie did both!)

GG also got involved in the production: Seohyun co-wrote "Holiday" and "Sweet Talk," while Yuri helped out with the penning the lyrics on "It's You."

Watch the videos for "Holiday" and the "documentary version" of the "All Night" video below, and stream Holiday Night further down.
