In October 2016, South Korean entertainment company Blockberry Creative revealed that it would be spending over a year to unveil its upcoming 12-member girl group. After introducing the dozen women through “girl of the month” solo songs and several subunits -- plus one Grimes feature -- Loona is set to release their first song “favOriTe” on August 7.

A just-under 30-second teaser video released Wednesday (Aug. 1) shared the first hint of Loona’s debut song, with member HeeJin, who was the first-ever Loona member revealed on Oct. 4, 2016, through her song "Vivid," walking into a room full of the rest of the members and declaring, "Hello! Welcome! I wanna try something now." A short clip of the song hints to it being be a sassy, brassy debut track.

Known as “Girls of the Month” or “Girls of the Moon” in Korean (??? ??), Loona have already gained a lot of attention ahead of their first release with all 12 members. Subunit Odd Eye Circle's Mix & Match EP went to No. 10 on the World Albums chart in October, and in May the third and final sub-team of Loona, yyxy, worked with Grimes for a short intro shout-out on their single “Love4eva.” Member Chuu also got a lot of attention through the LGBTQ-positive imagery of her music video for "Heart Attack."

Prior to their first, yet-to-be-revealed album as a full act, Loona released three EPs from the subunits --1/3, Odd Eye Circle and yyxy-- and a total of 19 singles. The group has gained a large fandom, known as Orbit, largely in part due to their incorporation of intertwined narratives throughout their music videos that tell the story of what has come to be known as the "Loonaverse."

The girl group will hold their first concert LOONAbirth on Aug. 19 in Seoul.
