This is NOT a duplicate of the sampler offered 20 days ago. (In fact I like this collection much better than that previous one.)
This sampler was actually offered a year ago and I downloaded it then... just re-played it to confirm the details. VERY GOOD.
There are ten instrumental cuts, mostly mellow jazz with a little bit of "swing." Lots of great piano work! (One of the instrumentals is a different style, rather march-like.) Also two vocals which are pretty good.
By all means check this out, if you like this genre at all, you'll love this collection! Great Xmas party background music, too.
