"Solo Queen" Sunmi will release her digital single album "Tail" on various music sites at 6 p.m. on February 23rd and start her full-fledged comeback activities.

The title song "Tail" is a song that compares delicate and agile cat characteristics to the love of an active, instinctive and confident woman. Featuring a different rhythm and catchy melody, the song was co-written by hit makers FRANTS and Sunmi, who have teamed up with Sunmi in "Porappippam," "Siren" and "LALALAY."

The choreography of "TAIL" was performed by Janelle Guinstra, a famous dancer and choreographer for Beyonce and Jennifer Lopez. On top of that, the choreography team Aura, which has been in harmony with Sunmi for a long time, added incredible subtle details, signaling an all-time best performance with bold and detailed moves reminiscent of cats.
