Every Oneus album is a well-made package of music, story, artistry and performance. With its latest EP, "La Dolce Vita" released on Tuesday, the group once again takes listeners on an adventure of new wonders.

In "La Dolce Vita," the quintet plunges into the depths of the ocean, like mermaids dancing with loved ones at night.

The Latin pop texture of the album's title song "Baila Conmigo" was the first inspiration to the mermaid story, according to the members Hwan-woong, Lee-do, Seo-ho, Keon-hee and Xion. The five-piece band recently held a joint press interview about the album in Seoul.

"We didn't want it to be obvious. Usually, people relate Latin music to something red and fiery, and we thought of a completely contrasting color -- blue. The mermaid story also popped up then. A last dance with one's lover that one could give up his life for was the perfect epitome of 'La Dolce Vita,'" Keonhee said about "Baila Conmigo," which in English translates to "dance with me."

At the base of "Baila Conmigo" is Hungarian Dance No. 4, upon which Oneus infused a moombahton rhythm, turning it into its own ode of passionate love. The song was produced by in-house composers of the group's label RBW.

"The song was already out when we were working on our previous album. We thought it was a waste if it didn't get the lead, and invested time and effort into developing it," Hwan-woong said, adding the bandmates were deeply involved in the song's making.

Now in their fifth year, the bandmates knew well on what they were good at and what they had to work on. Despite not getting credited, the members dedicated themselves to the production -- not just in creating the music, but the choreography, concept and visuals.
