Back in February, producer/rapper Cho PD announced that he was going to unleash a new boy band named Block B, whose roots would lie in hip hop. He created a unique training program which sought to cultivate their talents as artists, and not just as performers. Reportedly, they had to pen 100 songs to build their songwriting ability, and they also had to train with underground hip hop artists and choreographers. The hype for their debut just got turned up a notch after their debut teaser hit the web. The seven members of Block B are seen rocking the set of their music video, as they rap, dance, and lounge against luxury cars. Check out the teaser below, and then toss us your thoughts on this brand-new boy band!
