Native Houstonian DJ Mark D has been behind the turntables since the early age of 13! The beat made an indelible impression on him and life hasn't been the same since. In 2003 Mark D joined the XM Radio mixshow team and is heard by millions of people across the country. For 5 years you could hear his Air 81 mix every week on BPM. He left the BPM airwaves in November 2008 due to the Sirius-XM merger. You can now hear Mark D Friday Nights at 9:00 PM eastern at http://www.shoutdrive.com/
