I received this CD in a trade and am not sure excatly what the source ofthis recording is although clearly it comes originally from an FM broadcast.There are a few flaws (odd cuts) on this CD and a few moments where the DJ talks over the music. Nevertheless, if you like Run DMC, this is a special CDand 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 tightnotch filter over just the parts with the test tone. David - berger@lauan.com
