Great early sessions by Sonny Rollins. If you're even looking at this release, you already know that.
My review, and the 2 star rating, is based on the fact that this is another gray area copyright-expiration release. And my severe annoyance at the claim that this has been "digitally remastered." Oh really? Because the company that issued this doesn't have access to the master tapes. All they can do is take CDs that are already issued, legitimately, by his original record company, and use a graphic equalizer to mess around them to make them worse. You can do the same thing using treble/bass/midrange boost on your player.
This box is cheap, but so it should be, since the company issuing it doesn't have to pay royalties to the record company or to Sonny Rollins, who is still alive and assuredly could use the royalties.
All these gray market releases suck what's left out of the record biz and make it less likely that we'll ever see legitimate returns to the actual master tapes, and, in the case of a guy like Rollins, less likely that he'll even see returns for his own work.
Buy the box if you wish, but truthfully, the only difference between this and a download from the Internet is that here you get to pay a middleman who has nothing to do with the music.
