Some help required here please:

I've got a cool laid-back jazzy promo CD upon which the only 
decipherable details are grey grooves like vinyl printed onto the 
actual disc, with a silver razor blade that has a swirly symbol on 
it, the words "post production" and cat. no. NOZACD05.

Track 11 is a winner!

???  Anybody out there who knows what this is?
THANKS.
