INFINITE has released a teaser photo to announce the return of the subunit duo INFINITE H. The photo features Hoya (Lee Howon) and Dongwoo (Jang Dong Woo) along with “2015.1.26 AMOO.”

The ambiguous nature of the photo does not indicate whether “AMOO” is the title of their upcoming album or the name of a lead track.

INFINITE H was formed by Woollim Entertainment in 2013. The last release from the duo was the track “Special Girl” off of their extended play album “Fly High.”

“Fly High” was a hip-hop infused pop album which featured guest vocals from rappers Beenzino, Zion.T, Bumkey, and Paloalto. The album was well received by critics and audiences, with the duo primarily promoting the track “Without You.”

In 2014, Dongwoo appeared on the Costa Rica episode of “Law of the Jungle.” Hoya was featured on Henry Lau’s album “Fantastic” on the song “Need You Now.” He also appeared on the SBS music drama “My Lovely Girl” as Kang Rae Hoon, the leader of the fictitious pop group Infinite Power.

The last group releases from INFINITE include the studio album “Season 2” followed by the repackaged album “Be Back.”
