So much so, in fact, that in recent years the Dead's music has in many ways been less about who is performing the material than its everlasting spirit. To that end, in the fall of 2015, Weir and original drummers Bill Kreutzmann and Mickey Hart teamed up with singer-guitarist John Mayer, former Allman Brothers Band bassist Oteil Burbridge and longtime Dead associate Jeff Chimenti on keyboards to form Dead and Company. From their earliest days, when they emerged as the soundtrack of San Francisco's counterculture hippie movement in the city's Haight-Ashbury neighborhood, the Grateful Dead were notable bastions of inclusiveness. Now, with this newly assembled cast of musicians, that communal vibe has never been more applicable.
