wanting info for Duke Elliington - Digital Duke CD

I was wanting to buy this but it seems it's no longer available. I have searched the internet with no luck. Has anyone heard this disc and suggest an alternate. Or where I may find this one.

Digital Duke
Catalog #GRD9548
compact disc
reissue release date 1/1/1987
original releasing label GRP Records
I have it along with Dave Grusin's Hommage to Duke. Both are quite good.
Just adding that I first purchased Digital Duke as one of my first intro's to having Duke's music. Since then, as I take a pause, I now have more than several of Duke's Lp's & CD's. So I would encourage you, if you haven't already, to also seek out the " real McCoy".
