After a week off, the Grateful Dead‘s weekly Shakedown Stream archive concert webcast series returns this Friday, June 26th. Similar to the webcast two weeks ago, where the Dead revisited their May 11th, 1991 performance at the Shoreline Amphitheatre, the Dead will once again showcase a Shoreline concert—this time, their debut at the Mountain View, CA venue a few years earlier on October 2nd, 1987.
