A ton of interest has been simmering around SM Entertainment's old idol group Black Beat (active during 2000-2008), after it was revealed that these former idols are still an active part of the entertainment industry. They've swapped out their idol titles for behind-the-scenes roles as choreographers, vocal trainers, and DJs. In the case of Black Beat's lead vocalist, Jang Jin Young, he's currently working as a vocal trainer for numerous idol groups and SM trainees. He stated,�"Right now, I'm training one of SM Entertainment's new groups, who are preparing to debut; I'm also training the members of rookie idol group, Boyfriend." Jang Jin Young holds quite an impressive history as a vocal trainer, as he's known to have worked with SM Entertainment's SNSD and SHINee, and featured for solo artists DIA and A-mi. In addition, the singer finally released his first solo album after completing his military services last June. His album's title track, "Oh, My God", is about a man's joy and his heart-fluttering moments after meeting his eagerly awaited lover. Meanwhile, fellow members�Sim Jae Won and Hwang Sang Hoon have revived in the industry as a DJ performance team called�BeatBurger. The two members are also working in SM Entertainments as choreographers and dance trainers for idols like�TVXQ, Super Junior, SNSD, BoA, and f(x). Performance-wise, BeatBurger has been actively performing at night clubs, and were included in the lineup for this year's "Jisan Valley Rock Festival 2011". They will be collaborating with guitarist of rock band Schizo, Joo Sung Min, who will be accompanying the duo's expert dancing with his live guitar. Source: Star News via Nate
