You mention cd's....I found Arkiv music for Classical cd's and Classical Archives for downloads...are you looking for Jazz cd's or specifically Jazz downloads.You will not find a Jazz site like Classical Archives (downloads) for Jazz,but there are some sites that may be a little off the beaten path for Jazz...What are your interests? The more specific you are, the more focused my recommendations can be for locating cd's.
Is there a jazz equivalent to 'Archive Music'?
The online vendor archivemusic.com has an absolutely fantastic selection of classical cds. I'm wondering if there is a company that offers the same kind of selection for jazz? Amazon is pretty good, but I prefer to give my money to specialty businesses when I can.
