This has been available for purchase as a download from David Grisman's website for a while. Now a factory-pressed CD version is going into general release:

Description
The informal once-in-a lifetime jam session that brought guitar icons Jerry Garcia and Tony Rice together with their mandolin-picking host David Grisman was recorded in Dawg Studios on two successive evenings in February, 1993. The Original Pizza Tapes CD which included only part of that historical meeting, soon became an acoustic classic and one of Acoustic Disc's most popular releases.

The Extra Large 170-minute edition of this legendary session, includes the entire session with 16 previously unissued alternate takes in addition to the original master takes in their original sequence. This unique collection also features more of the personal repartee, which made the original release so endearing and insightful - the anatomy of this very special jam.

I ordered this a couple of years ago from Acoustic Disc. It's on 3 Professional CD-R's. These are Silver Discs. They did the same thing with the Old & In The Way Boarding House shows. Downloads and CD-R's and then a year or so later, they released them on Silvers. It pisses me off to no end.
