Next up on Grin Music we have the first single off Demarkus Lewis' upcoming album due out in May 2010.   Here we see DL give you a little preview of what's to come with Behind Closed Doors . On the vocal support we have the one and only EMan from NYC. Those who know hits know that EMan took part in one of the best selling House anthems last decade with ' It's Yours '. This time EMan lends his vocal stylings to Demarkus to top off this record which is sure to get the floor shaking.  Demarkus also called on (Chicago's Favorite Son) Doc Link with EMan himself to give their interpretation of the message. So come along as we take you to new heights.... Behind Closed Doors!
