The first time I really heard of Grandmaster Flash was with “The Message” http://www.dailymotion.com/video/x18lrg_grandmaster-flash-the-message_music#.UezQuBa4L8s
When you saw his name out front you thought he was rapping, but then here comes Melle Mel, who was also a huge inspiration to me. He dressed like a crazy punk rock star, with the fur jacket, leather hat, and metal studs all over… but he was also the first MC I ever heard whose lyrics were righteous and had substance. I used to hand-write those lyrics to show my Dad to convince him that hip hop was an art form of great value. True story.
If you ever want to hear Melle Mel in rare form – PREACHING! – listen to him rap about society and life and justice and injustice in the second verse of “Beat Street Breakdown.”
Note that in the video below, the “rapper” is the actor in the movie, while the voice you hear is Melle Mel: http://www.youtube.com/watch?v=QrfO6kW8EIs
