From Wikipedia:

Dead & Company is an American rock band that formed in 2015 with a lineup of former Grateful Dead members Bob Weir (guitar and vocals), Mickey Hart (drums), and Bill Kreutzmann (drums), along with John Mayer (guitar and vocals), Oteil Burbridge (bass, percussion, and vocals), and Jeff Chimenti (keyboards). Jay Lane replaced Kreutzmann on drums in 2023.

Dead & Company primarily perform Grateful Dead covers and is credited with popularizing Grateful Dead music to a younger audience. In 2023, Lane replaced Kreutzmann as the band’s second drummer for their final tour. Their final tour was attended by over 840,000 fans, with the final show taking place in San Francisco, the birthplace of the Grateful Dead.

At the tour’s conclusion, John Mayer reassured fans that “Dead & Company is still a band,” but the timing of future shows was uncertain. Several months later, the band began a residency at Sphere in Las Vegas consisting of 30 shows from May to August 2024. The band returned to Sphere for an 18-show residency from March through May 2025.
