At their May 5, 2017 concert at the
Nippon Budokan, Luna Sea announced that a then untitled new album would be released within the year.
Ryuichi also said that the theme of the album is "Love." The album cover was designed by graphic artist YOSHIROTTEN. The album's eighteen-date The Luv -World Left Behind- tour was set to begin with two concerts on January 27 and 28, 2018 at Mori no Hall 21 in Chiba, but these shows were rescheduled to May 23 and 24 due to
Sugizo having the flu. Instead the tour began on February 3. The opening track "Hold You Down" was originally composed by
Inoran, who compared it to "Absorb" from
A Will.
Maki Ohguro provides backing vocals on "Chikaibumi", "The Luv" and "Black and Blue". "Piece of a Broken Heart" and "So Sad" were originally composed by Ryuichi with arrangements by Sugizo. Ryuichi and Inoran's
Tourbillon bandmate Hiroaki Hayama provides piano on "Piece of a Broken Heart" and "The Luv". "Ride the Beat, Ride the Dream" is Luna Sea's first instrumental track, originally composed by Inoran. "Black and Blue" was temporarily titled after the film
No One Knows About Persian Cats which greatly inspired Sugizo. ==Release==
