"Rave That Dirt Down Off Your Shoulder" (http://
My first ever attempt at a mashup was far too ambitious for my nascent skills. It would take actual musical knowledge--you know, of keys and stuff--to complete. (I have worked on a scaled-down version, but you may not ever hear that one, either.)
Anyway, Jay-Z vs. Swervedriver is the first mashup I actually completed. I must admit, a lot of credit (or blame) goes to Jay-Z for making these acapellas widely available. If I hadn't actually finished this mashup, I may have long since quit altogether.
I think, were Jay-Z's fans to hear of this mashup, they'd be like, "Great...another Jay-Z mashup." I haven't actually investigated that--it's just a strong hunch. On the other hand, unlike Jay-Z remixes, I don't think Swervedriver remixes come out every other minute.
So, when I had this in a halfway listenable form, I ran it by the good folks at Swervedriver.com (http://www.swervedriver.com/forum/topic.asp?TOPIC_ID=372) who provided some helpful comments. (In all fairness, WTS also made many of the same comments. However, he is half deaf, so you can't blame me for seeking a second opinion.)
