Microphone check, one two one two. Back in the day, JYP (Park Jin Young) recruited Oh Chang Hoon along with Song Ho Bum to form the hip hop duo One Two. JYP had high hopes for the duo and went on record stating, "Of all of these singers, I thought that One Two would probably be the biggest hit." He also said that out of all the albums he's created, One Two's first album was his favorite. "I wrote all the lyrics and arranged the entire album. All the songs were of stories that would happen in a nightclub and they were so realistic, I thought that it would be an automatic hit." The group did have one hit single with "Here, Hips!" in 2003 which featured Rain / Bi and g.o.d. but unfortunately they failed to live up to expectations and left JYP Entertainment after their contract expired. Since then the group has been lingering around releasing various singles. Now, they're planning a comeback and releasing a new singles album titled ??? ??? Walala Lalale on February 24th. The group has released a video teaser for ??? ??? Walala Lalale. It's a dark teaser and has a scene where a girl is murdered. Seems very interesting, thanks to jenna19 for the tip and check out the teaser below.
