Starting tomorrow, all of the Grateful Dead live performances that are currently available via the Dicks Picks and _Vault_series also will be accessible as downloads. The ITunes Music Store will offer these for sale as it currently offers the band’s studio releases. Of additional interest to many Dead Heads is the fact that while the release of archival performance CDs will continue, some additional shows will also be made available exclusively via ITunes (with no specifics confirmed as yet).
