I Received This Cd In A Trade And Am Not Sure Exactly What The Source Of This Recording Is Although Clearly It Comes Originally From An Fm Broadcast. There Are A Few Flaws (Odd Cuts) On This Cd And Few Moments Where The Dj Talks Over The Music. Nevertheless, If You Like Run Dmc, This Is A Special Cd And The Music Sounds Great! When I Received This Cd, It Had Test Beeps Placed Over Most Of The Swearing On This Cd. I Removed Them By Applying A Very Tight Notch Filter Over Just The Parts With Test Tone.
