Grateful Dead spinoff group Dead & Company is calling it quits. In an Instagram post on Friday, the band, which features John Mayer alongside surviving Dead members Bob Weir, Mickey Hart and Bill Kreutzmann, said next summer's run will be its last. "As we put the finishing touches on booking venues, and understanding that word travels fast, we wanted to be the first to let you know that Dead & Company will be hitting the road next summer for what will be our final tour," the statement said. "Stay tuned for a full list of dates for what will surely be an exciting, celebratory, and heartfelt last run of shows." Dead & Company formed in 2015 following what were advertised as the Grateful Dead's final shows at Chicago's Soldier Field. The group has never featured Dead bassist Phil Lesh, who continued with his solo career. Since then, Dead & Company has toured consistently and kept the Dead's beloved music alive for a new generation of fans. As of now, the band's only announced 2023 dates are at their annual Playing in the Sand festival in Riviera Cancun, Mexico, which will be held Jan. 14-17. Last year, we took in Dead & Company's three-night stand over Halloween weekend at the Hollywood Bowl. Here's our recap of what took place.
