As reported, the band Dead & Company has teamed with nugs.net to launch LiveDead.co featuring live downloads and streams of every summer show as well as a few live video webcasts in selected markets. nugs.net has shared a preview of the upcoming Dead & Company SPAC webcast by unveiling pro-shot video from the band’s December 28, 2015 performance at Bill Graham Civic Auditorium in San Francisco.

In the 20+ minute video below we see Grateful Dead members Bob Weir, Bill Kreutzmann and Mickey Hart as well as John Mayer, Jeff Chimenti and Oteil Burbridge tear through “Slipknot!” and “Franklin’s Tower.” Mayer and Chimenti shine in particular throughout the improv-heavy sequence. Weir fronts the group on “Franklin’s” and throws in all sorts of growls and accents to his vocal delivery.
