Can these cd be bought? I am specifically looking for a track on the usher demo disc that included a guy banging on his drums for several seconds(It was incredible). Anyone happen to know the name of the track?

As far as I know they give those CD's away for free when you buy a pair. I have one that I've ripped into flac but it's 24MB per track. I don't know the name of the track, the CD doesn't come with track listing on the cover.

I still have my demo disc from when I attended the 2007 Home Theater Show in New York. Lots of deverse music on it. 18 selections to be exact and I believe the cut you are interested in is #9. I don't listen to it much anymore so I'll send it to you if you want it for your collection. PM me your address and I'll send it out. Elisha
