After a long wait, Rain and J.Tune Entertainment boy group, MBLAQ has finally released their teaser to the MV of their debut title song "Oh Yeah". This 40s teaser is just the first of the teasers that they will release. The song is unique, and the teaser gives a black & white sensational feeling, which fits because they are called, "M Black." MBLAQ had recently, on the 9th and 10th, performed for Rain's Legend of Rainism concert tour," where it was said that they were impressive. But because there were no official videos or pictures of their performance, it brought up many curiosities amongst the fans. This, and the fact that it was revealed that Sandara's brother was in MBLAQ, created a lot of anticipations by many fans, as they were the most browsed topic in portal sites amongst netizens through the week. I think the teaser teased me great, as I can't wait to see the official MV! Stay tuned, as they will release their song on the 14th, as well as debut on the 15th through Mnet's M! Countdown. Fancam of their performances at Legend of Rainism concert if you can't wait. credit: o0oLjnho0o Many thanks to kathyang and the mblaqattack forum.
