Wande Coal will in a couple of months unveil his record label called BLACK DIAMOND. The label is already registered and has 2 artistes on it with their singles to be released in 2013. The record label, which is being managed by Wande’s manager Abbey Nana, has been Wande’s dream dream since his days at Mo’Hits before moving on with Don Jazzy as an established artiste under Mavin Records.
Sources close to Wande disclosed to Music Gist that he was inspired to float his own label about 2 years ago when he started having problems with D’banj over the release of his 2nd album. He made efforts to leave Mo’Hits Records but was held back by Don Jazzy who promised to straighten his career for him no matter what.
That Wande is floating his own label might give people reasons to speculate a fight between Don Jazzy and Wande since he is signed onto his label Mavin but we can authoritatively tell you that they are on good terms and have an understanding about Wande’s move. Don Jazzy ,we learnt ,has given Wande the grace and support to float his label and also promised to support him.
