They promised it was coming this summer. They teased us with a few days of Dead programming on channel 17 Jam On. Now, the date is set for Sept 7th. Hooray! Looks like they plan on kicking it off with a show from the Hollywood Bowl from '74. I took a look on etree.org for the show and it looks like 7/21/74.
