Blood Moon is the sixth extended play by South Korean boy band Oneus. It was released by RBW and distributed by Kakao Entertainment on November 9, 2021. The EP contains seven tracks, including the lead single, "Luna".
Prior to the release of the EP, Oneus held an online and offline concert, "Oneus Theatre: Blood Moon", in Seoul from November 6 to 7.
On November 9, the group released their sixth EP Blood Moon, with the lead single "Luna".
Billboard described "Luna" as "the celebration of classic and modern-day sounds" by "blending of traditional instrumentation with dreamy synthesizers", and similarly NME described "Luna" as "a homecoming of sorts", balancing between old and new with "gayageum strings warbling over trap beats touched by âÂÂ80s synthwave".
On November 17, the group earned their first music show win of their career with "Luna" on MBC M's Show Champion.
