Cho PD's hip hop brainchild, Block B, is busily gearing up for their debut next month.�While the members already have ample experience promoting underground as well as extensive training by Cho PD himself, many wondered what other skills the boys had besides their killer composition and rap skills. Recently, a rehearsal video of the group taken a few months before the addition of their two newest members has been making rounds amongst netizens and building anticipation for their debut. Because the members are known for primarily promoting underground, Cho PD was asked about their potential of going overground. He replied, "I could just feel his potential when Zico, the team's leader, first sent me his demo tape when he was 17 years old.�He gained experience as a rapper underground for two years, but has since been receiving training in performance and choreography with the other members to finally make the transition overground." Block B will be making their debut on April 14th. Source: Seoul News via Naver Tip: Megan
