The Grateful Dead is showing a touch of grey as the band turns 60, and San Francisco is pulling out the stops to celebrate: tie-dye buses, banners across the city and the revival of Shakedown Street, the pop-up market that appears at Dead shows. The party culminates with three-nights of Dead & Company concerts from August 1-3 at Golden Gate Park’s Polo Field featuring band originals Bob Weir and Mickey Hart, along with other artists including John Mayer. We’ll talk about the long, strange history of the Dead, and hear about what the band has meant to you.
