With its 30-show Dead Forever residency at Las Vegas’ Sphere, Dead & Company has written another entry in the Grateful Dead’s 60-year legacy of live music reinvention. Beginning in late May, the band – comprised of founding Grateful Dead members Bob Weir and Mickey Hart, alongside John Mayer, Oteil Burbridge, Jeff Chimenti and Jay Lane – has delivered a series of three-night runs, each without song repeats and featuring a rotating carousel of visuals ranging from diaristic photo collages to abstract technicolor animations. For Dead Forever , which wraps this weekend with three shows Aug.
