Video Highlight- Jam Master Jay & Grandmaster Flash Performances

Today marks ten years since the death of the legendary DJ Jason Mizell a.k.a, Jam Master Jay.
This video features performances from both JMJ and fellow DJ Grandmaster Flash on MTV (when it wasn't just pregnant 16 year olds). I'm not sure exactly what year this video was filmed in, but I'm assuming that it's from somwhere between the mid 80's and the mid 90's.
Enjoy the video and RIP to Jam Master Jay!
